- Hello CZcams,
In this video we will be going back to the basics. Working with a lab bench power supply is essential to working with electronics so it's important to understand how to use one properly. As always, let me know down in the comments what I got wrong.

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
Thank you for this video. Just picked up a power supply and this helped me understand how it works.
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.
same!
Very good education right there. Thanks.
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?
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.
Very helpful video. Thanks!
Thank you for this...def needed
Awesome tutorial!
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.
I was looking for a dc power supply, only for ny hobby and this is great!
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.
Thank You!! I really appreciate the support. Just moved so I've been busy but I will be posting more videos soon.
How is your power supply holding out? Thanks
I will probably get the same model, as it has the "output" feature. Thanks
@@engineerjoules7163 Can you please tell me something. Suppose I pull a motor from a computer disk drive. Can I use the DC power supply to learn what the ideal voltage I should run this motor at without damaging it? Or is the only way to know is to risk destroying it?
One of the most important things to learn is the dangers of grounding to the wrong point on a mains earth/grounded oscilloscope or o-scope.
Hey EJ. Had to push you over to 1K! thanks for helping me out on this issue.
Thank you! I have to jump start some Apple Watch batteries and didn’t know anything about the DC Power Supply!
Very helpful. Thank you. Good content and pronunciation. Subscribing now.
Great stuff. Keep it up!
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!
great info
Thank you!
You explain very well
Thank you!
Really helpful video
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
Just found this channel, keep posting more!!
Dunno if you guys gives a shit but if you are bored like me during the covid times then you can stream pretty much all of the latest series on InstaFlixxer. Been streaming with my brother lately =)
@Charlie Alec yea, been watching on instaflixxer for since november myself =)
Thank you so much.
sir tnks.alot your video
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?
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!
Hey man, you seem to be in a similar situation to me. Im trying to make copper oxide, if you search how to make Copper oxide with electrolysis, the guys channels name is in for the penny. In his video he was running 6 Volts and 8 Amps to 2 copper electrodes in a salt water solution. I can only get mine to run maybe 300 milliamps max. I cant change voltage to whatver but it doesnt change the amperage. Could you maybe help me? I saw your comment and was hoping id get some clarity but alas i have not. Increasing voltage doesnt seem to increase current in the electrodes.
@@thecitrusfrequency6503 I'm not greak with electrical systems, but I can do my best. What is your power supply rated for?
@@thecitrusfrequency6503 If you post a video showing your setup and what is happening that you can show me it might make it easier.
Please post more videos... espicially on power supplies
*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?*
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 power supply stays at zero when trying to set ano draw cap. Any ideas? Great video
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.
Nice video, but how to output the current if you dont have that button?
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
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
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.
Nice video
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 ?
but you could apply 3.24V and way more than 80 mA, you would just fry the led right?
Thanks
can we use it as " Spot Welding Machine"
Respect
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
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?
That is happening to one I just purchased,, I wonder if its broken?
Edit: The only time I can adjust amperage is if Its connected to my battery. I tried to hook it up to a volt meter and i couldnt adjust amperage. That is potentially the reason why we were having trouble. Hope this helps anyone else. So in order to adjust amperage you must be connected to what you want to charge.
I've had the same problem...I have a Eventek and I can't adjust amperage.
@@BigHemiNJ leads must be shorted to adjust amperage. you are setting max allowed amperage. Then disconnect leads from each other and set volts.
Does it spike when you turn off the unit
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?
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..
Can i use a DC power supply to test led's instead of a simple led tester?
Do you have an exact link to this unit. Put it in Amazon and I'm not getting the exact unit.
How to use this as short killer withoit modding psu ???
Im still confused if such power supply provide symmetrical voltage? Like for op amps, eg "-12" "0" "+12"?
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 🤓
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
Can you recommend me a good book on power electronics? Thank you in advance.
Idk if I'm using mine wrong but whenever I set the Amps to anything it just displays 0 after setting it?
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?
Theoretically... yes. Just be careful, car batteries are high capacity and if you try charging it too quickly, you might overheat the power supply. set some limits and keep an eye on it.
@@engineerjoules7163
Thank you!
@@engineerjoules7163
And how would you go about it?
The voltage is to be fixed to 12V. With how many amps should I start?
@@aleksandarsrdanov1171 No, you do not want the voltage 'fixed' at 12 volts. A 12 volt car battery is actually 13.6 volts when fully charged, so you want approx 14.5 volts to charge it. Your amps are typically about 2-3 amps for a slow trickle charge, or 4-6 amps for a medium charge rate, or 8-12 amps (or slightly more) for a fast charge rate.
With this type of variable DC power supply you want to set the max voltage limit and the max amperage limit before you do the actual charging.
@@markstone1619
Mark, thank you for the detailed response. In the end, the Lab power supply I ordered has not arrived and it turned out my car battery is completely dead. I had to buy a new battery.
Cheers!
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.
LEDs and other semiconductor components are not acting linearly, therefore Ohm's law doesn't apply to them. Look at V-A diagram for LED to understand its behavior.

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!
