UPDATE: I screwed up the noise measurement. It's actually way better at about 60mVp-p no load and about 100mVp-p at 6A using a proper scope probe in X10. I was using a BNC cable with banana plugs and forgot the 50ohm series matcher. Oops. Will have to do another video showing this. Good excuse for a video on this topic anyway.

Apreciaate very much opening yourself to these cheap equipment, cause there are many of us who can't afford expensive equipment that is going to be use in home-entusiast aplications, and having your respectable opinion on these afordable stuff is very very useful. (Sorry my english, from Mexico by the way)

Oh I do so hate it when our marketing manager comes over and twiddles with my knob... so annoying.

I've been waiting for your review of these, I was holding off buying until now. Thanks!

Wow, Literally was looking at one of these on ban good last night! So glad you made a video!!

Wow. Forget the PS, i'll buy the case for my own project. That's a nice case and way cheaper than a similar project case from Digi-key. And it comes with accessories.

You are awesome Dave, Thank you for all your videos, I love watching and learning from them.

I have an old 19V laptop power supply (60W I think), all I need is a panelmount DC barrel jack into the smaller case and I should have a handy little bench supply. Looking forward to this. Thanks for doing the thorough review!

The battery charging terminal includes protection to prevent back-powering the supply if the mains is disconnected, and reverse polarity protection to prevent blowing the crap out of the unit (or at least the fuse) if you connect the battery terminals backwards, which has been a complaint with RD supplies in the past (-_-). You wouldn't normally use it outside of charging applications as it would reduce the efficiency and maximum power handling. Noise issue seemed clearly wrong. If that is switching noise, whats the higher frequency lower magnitude crap between pulses? There shouldn't be that much external noise coupling onto the signal. Also using an adjustable load for such measurements is usually a Bad Idea (tm) Their DPH modules are buck+boost, so you can eg use a 12V or 19V supply and get the full 0-30V output range. I don't think they have an equivalent in their new RD series just yet. The serial connection on the DPS/DPH units used a MODBUS implementation, hence the slave address selection. They do document this protocol quite well. It was fairly easy to build custom software to interact with, and it's supported by third party stuff such as sigrok etc. Looks like these new RD units use the same interface.

For the price, not a bad deal.

Great day in the morning! Your knowledge is IMPECCABLE! Cheers my friend! Thanks for the knowledge.

Just built one last night :-) Works well so far!

Seems very decent for the price.

28:52 I feel like this interface was designed by a technician from Hyundai. I rented one of their cars last year and was BLOWN AWAY by the thought that went into everything. Their menus and options were highly intuitive and allowed a lot of customization. Not only that, but the steering wheel controls, the media unit, the side panel controls, adaptive cruise control, it was amazing. I just really wish other companies put that kind of effort into their design and think about how the consumer will actually use the product - like the buttons and knob not doing anything unless you select a function to avoid marketing manager idiots.

Well, my RD6006 finally arrived a few days ago, with the chassis and 60V DC supply arriving sometime mid December, though I ordered all three at the same time. So far, I'm really liking this thing. I got the 60V supply, so with the forward voltage from the regulator itself, it's maximum output is 58.48V DC at 6.1A. The DR6006 unit will take up to 70v in. The graph display is actually pretty useful, because if you use the jog wheel, you can change the vertical scale (notice the division readout at the bottom) and see the amperage and wattage, so you can plot your device's current draw over certain times of it's usage and determine what kind of power supply and fuse your prototype device will need (you could calculate that before hand, but you could end up with something way overblown for what you actually need). I was just using it as a makeshift supply to test a force feedback joystick, and was able to graph the current change when I moved the stick. Presumably this kind of logging is what the software should be used for, but with the antivirus complaining like that, I'd use an isolated system if you need to interface with it. At least until somebody can reverse-engineer the code and determine that there's nothing untowards going on. It should be noted that there is other software from more reputable sources that recommends that you disable the antivirus while you install it, so this isn't exactly anything new. It may be nothing of concern, but exercise caution until you know for sure. I also discovered that the voltage monitor works even when the supply is off. Probably for the battery charge function. I wouldn't use it for a multi-meter, but that's a curiosity. The chassis and power supply fans only go on initially at startup, and thereafter only when they're needed, so it's completely silent when on standby. That would probably change if I find something to do with it that requires higher current, but with what I'm doing, it runs pretty quiet. So far, it seems like a good buy if you get the components on sale. About $170 CDN for the whole lot on sale (on Banggood.com), including shipping, which is far cheaper than a comparable name brand supply, even off of eBay. We'll have to see how well it holds up over time, but based on what I've experienced so far, and Dave's own review, I'd definitely recommend this for electronics hobbyists looking to get their lab going at an affordable price.

Well had it over 12 months now and still pleased with it. I have used it hard charging some big batteries. So have pushed to limits and still going. I did get the full Monty with all the suggested units direct Tom manufacturers. Good review nearly need to watch the follow up 😂

Would definitely be interested in an output filtering video. Thanks for the review!

Interesting PSU. The DC input is great for me as I run my inverters off a 48V DC battery system here so I can just add another breaker to the LVD :) I'll hang on a little first to see if anything can be done with the output noise before I get one.

Mine just came in, very nice ......thanks! Struggled to source 60V backend PSU, so bit the bullet and ordered a 60V form their recommended supplier.

I've reviewed mine and I really like it. The graph mode is cool.

Was that fuseholder damaged in the meanwell PSU ?. It looked like one of the legs was splayed open.

Looks great! Might have to get one of these!

Great video and I appreciate the effort you put into this.

Your excitement is great.

Incredibly deceiving title when you factor in the price of the case and actual power supply. It's really a $160 power supply. I've seen some actual $50-$60 bench power supplies for sale, would love to see a video on one of those.

33:40 The only difference I could tell with battery mode via the green post is that it actually shuts down the output when the battery reaches the desired full charge level as opposed to a regular power supply or when using the red output post.

Was waiting for you to review it before buying it. I'll get one and see if I can improve that ripple and if it works I have a nice case and some toroidal transfomers that can easily hold 2 of those units.

19:03 If it's bolted to the enclosure, I think the screws would provide enough contact for grounding, might not need to scrape the paint, but definitely would test it in diode mode with a meter. Cheers mate, I've seen a few of your videos before and have glanced over the KZfaq recommendations because I didn't wasn't in the mood to think in depth. The few videos I watched tonight were very interesting and I look forward to your more recent and upcoming videos. I see a 2kw PSU video is "up next", _ctrl+click_ that into a new tab for later.

15:25 the reason they do not have an enter button on the scroll knob is because you are very likely to rotate the knob while pressing it, thereby messing up with your settings. It's human tendency and I think a seperate enter button is perfect.. although I would have appreciated a dedicated enter button right below the knob.

The voltage graph display mode is obviously for charging batteries and tracking their charge progress!

One of the spring clips on the ceramic fuse of that RSP-320 looks real average ay. Great video tho!

love your videos, you make learning things about electronics entertaining

That is one beautiful case for one hell of a price

Yes please make a video fixing the noise, my bet is the MOSFET or Diode needs a ferrite bead slipping over it.

The back to the future jokes always get me. Nice video man

Don't know if they fixed it but we had problems with Win's auto install version of the CH340 driver a couple years back. The official one works perfect.

I was considering buying one of these from Banggood where it was $10 cheaper than this AliExpress price, but I don’t have a high voltage DC power supply that could make full use of this thing’s output, and to buy a power supply would double the overall price. I did get one of those tiny little bench power supplies and have it connected to a big 24 volt power supply, and it works surprisingly well with excellent accuracy.

Battery wasn't included for shipping reasons.

Nice video, This help tip me over into buying a 6012 and 6018, which have the same noise levels as the 6006 (at the same current level) the noise only rises after that with 160mv p-p at 14vdc 10a, and increases rather linearly. You can disassemble it, as the banana posts while soldered have cutouts in the front panel, so they can just pull out of the front panel with out desoldering.

Thanks. I actually look into these. Have a wish to make flat lab power supply for non-exorbitant price for my home DIY needs and this controller seems perfect for that.

The drop in efficiency at 4A is when the fan turns on - it is current controlled, not temperature controlled

My uncle Bob thought it was bloody brilliant, so i wrote my mom about it. Gotta tell you, nothing to sneeze at, remarkable value. 😁

You are awesome, Dave. Men like you should live forever. Then we would have videos from you forever. I guess we would all have to live forever. I'm up for that. Anyone? ;-) Thank You for your spirited delivery and "bottomless" knowledge.

What i really like most is this nice and humble oscilloscope.

It's been mentioned once already, but I thought I'd bump the observation: The fuse clip in the 48v supply needs some attention. It's noticeably bent and may prove to be an imminent failure point.

Is it radiating switching noise too? Maybe you could do a video on how to reduce that high freq ringing by adding an RC snubber circuit.

For the first time I have something before EEVBLOG. I'm quite happy with mine. The recommended power supply is taking ages to ship though.

Also, thanks Dave on the reminder about the OVP. My RDtech for the bench supplies my headphone amp. It's input bulk cap is a 16V 400uF. That little PSU will happily with a spin of a knob put out 50V. BANG goes that cap inside my headphone amp case.... and anything else similarly limited on that rail which may NOT be in a case. I should set it to 16V as a secondary protection against "Whooopsies". If I need more it will remind me to clear off the other devices from the rail first.

I'm not sure this thing is worth getting over the venerable KA3005 Korad(or rebrand) power supply, unless you already have a bulky DC supply itching for a front panel, but even then, korads, for around the same price($100-150 for everything) are fully linear power supplies.

keep reviewing things like this Chinese stuff is quite interesting

I have this exact same - from 8-1-2020 - exact same settings, both USB and WIFI, all works just fine. The "virus" is concerned, it has NO VIRUS in the software, at least not when I scanned it with MS-Antivirus and AVG + some other scanning softwares, found 0 viruses! For the money it is a great value! It isn't for everyone - like the noise problems, but for most people this shouldn't cause any problems. Thanks for the video.

I really liked your video on the RD power supply housing and bought one for my DPH3205. Before I installing the 3205 I attached the p.s. housing to a 12v battery, switched on the housing at the switch to make sure no smoke, and measured the voltage that would be delivered to the 3205 at 12.67v. That looked good. Then switched off the p.s. and measured the internal voltage at 2.7v. As a sanity check I disconnected the battery and the volts immediately dropped to zero. There seems to be a residual voltage when the p.s. is switched off. Should that be the case, or is that to be expected?

I've always wondered why these things done exist that just plug up to an atx power supply. They are ubiquitous, and provide multiple voltages.

Wouldn't it be advantageous to mount the MeanWell supply on standoffs, so the air can flow under it? The whole bottom of it is a heatsink.

Thanks Dave!

this is great, i can cross this one off the birthday list. noise is a Ham's worst enemy. thanks for the review, as always awesome job mate.

18:00 looks like that fuse is barely in there and would fall out as soon as you shake it.

Dave: I use the power supply to Power the power supply

Hello! Excellent Vid! Came to comment that the 2x4 female terminal on the back end looks exactly like one designed to fit an NRF24L01 Wifi module! Looks like the pins match up as well as the fact it runs on 3.3v as seen in the vid. I hope this helps!

Yeah, their extra fan in the case that always runs is a Ruideng specialty. Same for the older, smaller cases. I just made a fan duct for the load-controlled fan on the device to make that one suck the air into the case.

"Idiot marketing protection mode" I'm sensing a story behind that, Dave. How expensive was the damage, & was he punished for his crime?

Doesn't seem worth it once you factor in the power source, case, etc. You can get the Korad PSU for around $100, and it's ready to plug into the wall.

Dave, you should do a video on adding some output filtering to this.

Amazing. I paid $200 10 years ago for a USED 60V 10A B&K lab supply that is rack mount and makes me take a deep breath and grunt when I have to move it. I just love the size and price of hobby-grade electronics gear these days. From sig gens, to VNA's, to scopes, to power supplies, I find myself slowly shifting from using my boat anchor HP gear to this cheap, small stuff for anything that doesn't require max precision. And very little ever does.

4:05 "whhhyyyyyy?" made me laugh

Can we call a product “power supply” which doesn’t power from the ac mains? What is the difference between power supply vs. dc to dc converter?

I've ordered the components also , it it on it's way, 2 are in the destination country and 1 (the PSU) is in a airplane , so i think i can build it soon, ordered the recommended power supply so al should be well.

Love the daydreaming 🙂 it is a necessary step in first time assemblies.

The lab bench psu didn't kill himself

15:43 Having an AvE moment I see :D

This is one off the best video i ever seen on youtube,about elektronik! Must see if you by this.

Thanks for this Dave

No Wucka’s!! Bobby Dazzler!! Your gonna need another video on Aussie Colloquialism for our International friends 😂

15:44...close, but no cigar...I know, you're trying to keep it clean, but it only works proper if you use the right words for Focusing...AvE isn't wrong...LOL

36:04 My plan for a DIY hack-together is an old desktop PSU and I'll attach a boost converter board for instances I need more than 24V on my table. --Literally, I built a table, so far just with outlets and a couple switches, but I plan to incorporate the DIY lab bench underneath and "pipe" the power right onto the main work surface with banana plugs. Right now it's basically a soldering station and I've got a hot glue gun holster, but I plan to expand. Modular designs are very desirable to me, I want to ultimately plumb it with exhaust, propane, and an air line hooked to a compressor in another room, all with quick connect fittings so I can hook up multiple benches with perhaps 6ft hoses so I can arrange them in a garage, maybe with casters for easy moving and a welding bench - this is getting out of hand.

The communications for these is MODBUS, address 01. I will write my own software interface when i have time. GREAT review! thank you, Sir!

so I need a power supply to power my power supply?

So you need a power supply for the power supply?? This is neat and affordable, but its only half a power supply

Great Channel! do you have any suggestions for a linear dual power one with a good quality/price?

Appreciated, please test the short circuit test with full power, does it survive or out of calibration? PS: Experiencing a lot of low cost bench PSU didn't survive.

well that ain't no proper power supply. Its just a fancy regulator unless you can plug it into the wall ;)

2 fuses, must send this to weller

Looks like RD6006 is a hot topic on KZfaq right now. Multiple KZfaqrs made videos about it and got into my feed even though I'm not watching them and haven't watched this video at that point.

Cheap power supplies is buying used laptop chargers! Might only be at 19v but I guess you can put two in series if you need the voltage.

i have a 100v 50v center tap calling for this thing out of a 200W Kenwood receiver

Ordered it more than 20 days ago :( still in transit ...

@15:43 😂 his voice reminds me of the tucker character from “There’s Something About Mary” Great in-depth review 👍🏽

One of your links goes to Lighting Global Store that charges $20 shipping for US destination.

So it's not ACTUALLY a power supply - it's a REGULATOR.

I think there are lots better choices than this. Too many useless features and not enough basic function. By the time you have this configured to provide 360W output you'd be into it for $200, and you'd still have all that noise. There is a thing on eBay called the Dr.Meter triple Variable linear DC power supply that provides 0-30V@5A + 0-30V@5A + 5V@3A. You can series the adjustable outputs for 0-60V@5A or parallel them for 0-30V@10A. That's a total of 315W. A buddy of mine bought one ($200) and it gets the job done. Construction was not perfect, but we spent about an hour rectifying things to our satisfaction. Less time than it would take to fully configure one of these switchmode things in a nice case and input power for 360W out. Far more real life versatility too. They can keep their RD6006 as far as I'm concerned.

That's terrible Muriel hahahha, Dave, so glad I saw this video, I've been needing a 'basic' benchtop for a while, I'm not doing any hardcore electronics like you are so having input noise is actually a good thing, ensures my circuits can handle it properly. Off to get one of these bad boys and the Meanwell right meow. Cheers! Appreciate it.

The separate case design is a nice feature in order to add the desired amount of weight to increase quality :D

Battery charging in bench lab power supply? Chinese style ;D

Those display colors are AWFUL! Reminds me of one of the original PC 'color' graphics modes!

RD Tech does nice stuff. They even have a YT channel, where they announce new products and give info on how to repair their stuff. I like the guy from RD Tech. I would like to buy one, but I don't need it unfortunately :)

I can certainly see some uses for this but frankly a bench power supply is one of my most valued tools and I really can't see going cheap on it. The last thing you need when troubleshooting are problems induced by noisy power. I notice you have a pretty good one also. 4 tools I suggest guys pay a little more and get a quality product are soldering irons, power supplies, scope and a good meter. Open up say a Tektronix bench power supply and do a side by side.

3:03 omg he just ripped it off :( slower = better

It’s fine but it’s half a power supply. I’m not sure it’s that good value.

I have a mean well beast brick. 48V 10A It's fan runs constantly from power on. However... if you put it under duress the fan has a LOT more to go. At idle it's at minimum. I remember getting it really going using an RDTech module to charge a high charge rate Lipo at 12.6V 20A. It didn't take long for the fan noise to get much, much worse from both the PSU and the DC Brick. On the other end, I use an RDTech to manage a 12V solar feed for bench use. It's 5Amp and I never use half that, so I just cut it's fan lead with a pair of cutters and decided to install a thermal cut in later... it's still termporarilly fixed.

Thank you very much for this video! Now I know what I gonna get for Christmas 👍🏻
