This actually makes it make so much more sense. I was very confused and didn't realize the amparage was an amparage limit and not how much the power supply was going to output

Thanks! That was very helpful about the amp setting being more of a limiter and less of the amperage it is using to power your electronic.

Thank you for this video. Just picked up a power supply and this helped me understand how it works.

Very good education right there. Thanks.

Thank you for this...def needed

Very helpful video. Thanks!

Good stuff man. You helped this knucklehead out with what would seem normal questions.

Great vid. Will look at the rest of your vids as I’m just getting into electronics and loving it but all the stuff I find on yt are missing the beginning steps needed to understand how this all functions.

Awesome tutorial!

Super helpful thank you! you even added a few electronics basics and that's an awesome plus. Would you do a follow up about the ground?

I was looking for a dc power supply, only for ny hobby and this is great!

Hey EJ. Had to push you over to 1K! thanks for helping me out on this issue.

I just bought the same thing, plugged it in while watching your video. I am trying to learn electronics on my own. A lot of material out there, not that much about this item. Thank you for posting it, and I did subscribe so keep up the good work.

Very helpful. Thank you. Good content and pronunciation. Subscribing now.

Thank you! I have to jump start some Apple Watch batteries and didn’t know anything about the DC Power Supply!

You explain very well

Great stuff. Keep it up!

Just found this channel, keep posting more!!

great info

Just got one today and love this thing so far. I do I lot of car mods, stereos, servos etc. I don't know why I didn't invest in one of these sooner! Thanks for sharing your knowledge!

Thank you!

Thanks! I was wondering why/how its able to adjust both Voltage and Amps, knowing Ohm's Law. But I understand now that its the max limiter.

Really helpful video

Thank you so much.

sir tnks.alot your video

Thanks! I had some issues with a hydrogen generator I was powering with one of these, and I suspected it was because of ohms law but people were telling me otherwise. Now I know!

Please post more videos... espicially on power supplies

Thanks

Respect

Nice video

*Can you do a video showing how to connect to a headlight assembly and how to the set the proper voltage and amp needed to power the assembly?*

Bought a DC power supply for electroplating and testing out wires, but I'd love some suggestions as to what else this thing can do

Yes, an output channel button IS a standard feature. It's only missing from bottom of the barrel chinesium trash, which are know to spontaneously combust from various failed components like bad dipped caps. DO NOT use them indoors or for charging batteries or anything unattended.

My brand new PSU has OVP and OCP (overvoltage, and overcurrent, protection), but why if we are already limiting the voltage, and current, via the cv/cc options before we even apply the juice to the project?

Hi, I need some advice. I just bought a Power Supply Kococater SPPS-S605: 60V - 5Am, pretty similar to the on the video. Firstable I am not an engineer but I am trying to emule a device with this PS. I want to use from 1 to 50V and from 1 to 35mA. I tried and set up to 20V and 5mA, but when it was used, the display showed: V:4.8 (it was moving but just reached 5V, and the Amper value did not move, it stayed on 5mA, this is the value I wanted). Here comes my question: What should I do and order to get this measurements: from 1 to 50V and from 1 to 35mA (I need to hold the voltage without changing the miliampers). Thanks.

My power supply stays at zero when trying to set ano draw cap. Any ideas? Great video

I want to get a power supply that will work for me from 3.7 for some led lights and I want to be able to change to 5v 6v 8.7 9v 12v and 18v and I need to know if there is some component that I can use to restrict I want to use 18v millwalkie batteries to power lights on my bike but my signal lights will be 12v and probly the same for running light to eatherway is thereva resistor or restricted or what ever to allow 18v in but only 12 out or what ever I end up useing and yes it will be a mountain bike that I want to have signal and break lights on it any help you can give will be vary much appreciated. Thanx dale

Nice video, but how to output the current if you dont have that button?

I've seen some units that don't have a ground in some units that do have a ground plug. What is the purpose of that ground plug. Cuz I know negative is technically ground. So I don't know why ground is separate.

Do you have a video showing how to use the bench power supply to charge a laptop battery? Doesn't have to be fully charged but enough to do some troubleshooting on a laptop - unit runs off the battery but not the charger (don't think the battery is charging from the laptop either) a 30V/5A unit should be good. Thanks. is the brand you are showing a good one?🤔 Thanks

Do you have an exact link to this unit. Put it in Amazon and I'm not getting the exact unit.

hey mister? help.. my original xbox console says 220V-240V~1.2A 50hz, what should i use or to buy for my power cord? im from philippines with 220v mostly..

I have a 12v soundbar for a golf cart , ECO X GEAR , How do I hook it up to a 30v 10a DC Power Supply ?

My unit shows the dot in the second position (00.00 amps) and I saw many photos and videos like yours that show the dot in a different position (.000 amps)which means a different resolution, how do I change the resolution of the amps?

Is the "Tacklife" dc power supply you are using a good deal? Looking at other brands but don't want a cheap box! Thanks I look at equipment as an investment, & it's not worth buying a power supply that won't last, isn't reliable, not real accurate...plus I subbed 🤓

I’ve got an Eventek that is in a similar package to yours. I’m starting to wonder if it is defective though. The only time i can adjust amperage is if I short the leads together. Once it is hooked up to a load, the adjustment does nothing, but as I turn it, the led voltage reading disappears. Thanks for the video. Our first lab in class, the teach basically just threw the power supplies at us without explaining a thing about how they work. Is it any wonder that half the equipment in class is currently broken?

can we use it as " Spot Welding Machine"

Can you recommend me a good book on power electronics? Thank you in advance.

Assistance please.. I have an EC600-90 & iam hitting a limit led I need to use constant power when making nano silver . And iam no scientist so please keep it simple. Any help is appreciated. Thanks

Does it spike when you turn off the unit

Can i use a DC power supply to test led's instead of a simple led tester?

but you could apply 3.24V and way more than 80 mA, you would just fry the led right?

But how much you have to increase the current if you have a phone runs on 3.82 ? Sorry for my question but I am new and I don't know that much about it

Im still confused if such power supply provide symmetrical voltage? Like for op amps, eg "-12" "0" "+12"?

Idk if I'm using mine wrong but whenever I set the Amps to anything it just displays 0 after setting it?

How to use this as short killer withoit modding psu ???

How do I ground it properly :.(

I think it has more to do with law of transformers and not ohm's law.. ohm's law states that as voltage increases so does current.. This is not what's happening here, resembles more of how transformers behave.. Can anyone help?

Can a car battery be charged with this lab power supply?

"I will be posting more videos " Last uploaded a year ago 😢

Initially you applied 3 volts and saw .035 A which means: r = v/i = 3/.035 = 85.7 ohms. So the LED must have about 85.7 ohms resistance. Then you kept max amps at .08 and tried to apply 4 volts but it clipped the voltage to 3.24 volts... so: r = 3.24/.08 = 40.5 ohms. So the LED must have 40.5 ohms resistance. I don't understand how that can be. I'm missing something but... not sure what it is.

As an electrical engineer I noticed, Just by the way he explained things I don’t believe he is an electrical engineer! He doses have some knowledge about electrical engineering but that’s it

DC Power supply units which are 13.8v are power supplies for CB or Hamradios! İ have many 30 or 35 amp 13.8v power supplies for my CB radios!
