It’s always nice learning from a person who loves what they do. That’s why I’m here

Such a joy watching this! Thanks for the review and weighing the tradeoffs and advantages of different units.

It's nice to see how you do the test and inspection of the equipment. It's like you follow the same steps as much of us to do that, so, is pretty sastifiying. Keep that spirit!!!!

VERY GOOD VIDEO! I enjoyed that a bunch, and I always learn something from your channel.

Thanks Eddie. I'd like to see noise characteristics under full load.

Quick and great review !

Hi Eddie, thank you for a great video, your knowledge and your enthusiasm.

Thank you & congratulations for new episode variable power supply series 👏 💝

Regarding output terminals, I always prefer ground to be in the middle so you can ground either positive or negative side with a copper strip. Once you've done that, a dual banana plug can be used between the ground and the free side. Of course, you can get the best of both layouts by having the three terminals at the corners of an equilateral triangle, but that seems to be quite rare.

Nice attention to detail in the design but I prefer to have power also shown in the display.

Thanks for the videos on psus and doing the review on this model. I've been browsing videos up to a few years back looking for a solid recommendation. Would you still recommend a similar model around 100 like this after all these years testing low to high end machines or this machine compared to some of the new stuff on the market? I've been stumped on which to buy for under $1k. What are your thoughts for choosing between rigols build quality compared to siglent, vs tectronix/keithley for functionality and practical use or be precision? I'm a electrical and computer engineer student planning to set up my own test bench for projects and wanting to invest in something that would last for years through college and even for professional work. Plan on from working with circuitboards and chips of all types, pc components to drones, and ebikes. Was wanting something that fit the build of a programmable, multi output, high accurate clean psu. Been working with a lot of tectronix/keithley on campus but its a little steep for 800$ for a psu. Could you do a top 10 or something from your experience with the different companies products you've handled? Any advice with be very appreciated.

Nice power supply, looks well built.

Power supply for $320 + $100 shipping is considered to be a low cost?

Thank you Eddy . I have a dc electronic load from this brand as well as a rigol electronic load and guess what. I have found this Brand to be more accurate than Rigol. Today I fried my power supply and am going to buy this one. This seen to be very good quality. Thank you for the review

Was looking at possibly buying an Itech electronic load, wonder if they might send you one of theirs to review, they look like a company that build decent gear.

Nice safety package 📦 👌

Good supply for the things you do on your channel, good to see you found a PSU sweet spot. Looks like they went for "a HP look" which is a good sign. They had better have sorted its transient behaviour, as it looks like it has been designed to step or change voltages in an instant.

Air intake and outlet on the bottom front and rear of the unit, hot air will build up on top.

Eddie is always here to tell if it's top notch. Or does it ripple like butterscotch? Joking aside. It's a nice psu.

I try to watch all your videos.

Thanks for the video. After watching I bought the IT6721. I need some advise on how is the intended performance or use of this unit when powering circuits that do require both positive and negative voltage + ground. I am building a dual power supply using LM317 and LM337 but surprisingly neither the (+) nor the (-) voltage develops any tension to ground. Some of the boards I am working with, have components like the LM348 (for example) which requires +15V and -15V (no ground) but at the same time, some do have also other components (power transistors) which work using only (+) and ground. I bought the PS because I understood that the power supply has a couple of internal transformers, one of them a linear transformer which I supposed had a isolated secondary with its central tap grounded and connected to the pin in the front with the ground symbol as any derived secondary source should. Please advise.

Review the Siglent Technologies SPD3303X-E Triple Output Power Supply

Would be tempting if I needed such a beast. Currently $320 with a 15% off coupon on Amazon. Looks like mostly quality parts - Volex cord, NMB fan, etc. - but I don't like those Lelon caps. The only cap that ever blew up in my face was a Lelon. Also, the user interface looks rather nonintuitive. Never like to see a "shift" key.

Great review, I am wondering if you can take any two copies of a power supply and connect them in i.e. (-30/0/+30)? A bit of legal pedantry: I have to tell you that you are being sponsored if you in any way get or hope to get some advantaged that not everybody is able to get. Besides that, do you also have to specify, if anybody you know it gaining advantage, are working at that place or if you hope for any favors, are paying any favors or to make it short: "If anything is different from what everybody else who have bought for their own money" The law is very strict about that, and it has to be made clear and upfront from the start. :-)

Hi Eddy, I tried to click on the Kaiweets store link and it doesn't work. I get a 404 page error not found. The iTech power supply looks really nice also.

hello Sir. Thank you for Sharing. Can you please help me giving me a peice of advice. I am trying to buy an oscilloscope. I wasn't able to pick one between Rigol DS1104z-s plus and SDS1204x-e which one can you advise me please? thank you

looks like an ok power supply, programming is a nice touch. i'm not a fan of how they rate them. if the power supply says 8 amps, it should be 8 amps through the entire voltage range not just up to 20v then drops off. just depends on what you are use is i guess.

nice video! remember to swap the binding posts from you blacky PSUs.

Make your own with a transformer 4 diodes capacitor and a buck booster control

I always like having an output button. I like to set without endangering my ÐUT. But I am paranoid.

The way the display reads zero when you turn the output off is very strange. Should always show the setpoints when output is off.

Is it possible to get calibration information for this unit?

Sir please you, do you know any ic 111EU

So importing from China with taxes and shipping it is about £400 to the uk, has NO ability to be programmed. What it actually has is settings memories. You can't control it from another device like a computer, the user interface is non intuitive, it has lots of output capacitance, has no separate front panel voltage sense terminals and the manual is non intuitive. It also needs to be tested for undershoot, overshoot and noise.

I think the fan blows out of the back, so your airflow explanation is backwards.

between your politeness and the chinese' bad english, the only result i can see is greater confusion. I think you should be more critical and frank about their flaws, in spite of you getting free stuff, so that everyone learns more. like what on earth were they saying with that output curve example, specifically the last couple of lines? also, I'm just wondering about all the products on amazon that seem to be basically the same except for cosmetic differences. it would be interesting get a bunch of them and see to what extent the guts, designs and components are shared. i remember not long ago a viewer pointed out that one of the ideal multimeters you pitted against a fluke was actually an appa 99iii. and yeah, it looks like only the colors were different. then i discovered that appa have a 98iii and 99iv that also look the same so maybe the ideal and the appa weren't identical on the inside because the 3 different appa products wouldn't have been identical to one another on the inside with different names, one would feel safe to assume. also, when i follow links to the kaiweets products i find a bunch of identical looking products under different names or none at all. just a few days earlier I saw the same thing with a socket tester that won a fairly recent youtube shootout. the same product in the same colors with just the brand name, usually on one of the smaller panels but in the same font even. with the kaiweets stuff, it's almost identical regarding placement and colors except they've managed to hit the bit time and get their own special font used. this must've come at an extra cost but I guess now the template or screen for they logo is there and can be used by all of these manufacturers. I think someone needs to get to the bottom of it and for each product find out who actually made it, who designed it, who commissioned it, which factory its made in and which other brands have put their name on it. then we might be able to establish where all the different factories are, who the middlemen are, which companies work with with manufacturers and everything in between. we can then establish which factories produce the highest quality stuff, for instance. and we can establish exactly what all these other companies do, if anything but testing and selecting products to put their name on. having all these minor superficial differences gives the illusion that we have lots of options when all it could be is just a method to use a bigger net to drag people into purchasing essentially the same product. it distracts from other competition, wastes time, inflates prices in various ways including by having a big buffer to play with so that all these different versions of the same product have prices that fall within a certain range but vary in waves within that range. it's hard to explain but it's like a false reality, twinkling and distracting and at the end of the day it continues to lure people into pouring money into the prc instead of their own countries, just because something costs less. In turn, this is because people are paid less. And nobody cares that their money could be funding the weapons that could be used against them in future. Okay, why bring politics into this? Because if people continue to be ignorant, they'll continue to be taken advantage of and it's like the blind leading the blind into something they won't realise until it's too late. I've never been like this previously - I used to be an indealists and quite left of centre and lovely-dovey, 'treat people nice and they'll prove to be nice' type deal. but the enemy doesn't comply with these dogmas and use it to their advantage. they don't respect foolish people who will take the quickest and cheapest route to get a foot in the door, no matter what the greater costs are. I've been there and done that. and i've been grateful to the chinese economy for it but it's total ignorance and foolishness. i still wouldn't ban myself from buying chinese if it was too much of a tempting value proposition, especially because the politics side of things hasn't fully exploded and in general, the people involved in the business side of things is china are generally set apart from those in politics, for the time being at least. yet in saying that, ideology is very powerful and in spite of major civil wars, the chinese always teamed together when it came to nationalism and foreign invasions. they were always able to put their internal things on hold, especially once the machus were out of the way. oh politics again, excuse me. anyway with ebay, i used to choose the chinese option a lot but now that has almost completely vanished. it also helps that the chinese stuff had terrible postage times and that ebay has ebay plus benefits but some platforms like amazon even the playing field and still nobody considers where a product comes from, how it can be that cheap, who is the original IP owner and what are the consequences of diverting money into that particular land. All for what? coz we got something cheap or free? nothing is free and you get what you pay for. thanks for reading if you made it this far and youtube didn't delete it. :)

The user interface is cumbersome. Typical of a lot of modern stuff these days.

Thank you & congratulations for new episode variable power supply series 👏 💝
