How to Use a Power Supply

Bench power supplies, also known as variable power supplies, are useful tools for testing and debugging circuits, as they allow you to adjust DC voltage on the fly. Some units can be configured to act as a constant current source, but in this video, Shawn shows you how to use a power supply as a constant voltage source with a configurable current limit.

thanku for information

[@EVILUTION9]

How are you making those sparks?
Ultra cap discharge?

[@tpobrienjr]

Thanks!

[@onebeartoe]

Classic Shawn.

[@yashdavare1896]

Great!!!

[@pollydor07]

THANKS

[@mauricehatzke6119]

Do you have kits for your power supplies

[@scottl7644]

Dear friends.
May I ask if a 60v 5amp @ 150w bench power supply. Allow me to use 12v at just above 10amps for a diesel heater???
I know I can buy a 30v 10amp supply but my needs will need at times to supply 42v @ 2amps.
Any help would be highly appreciated ✌️✌️✌️
Sincere regards,
Scott. ✌️🙏✌️

I think i'm going to have to watch this video again tonight a few times When my brain is awake 😂

[@TheMono25]

Does anybody have any recommendations for my first power supply I was hoping to get something with oscilloscope I am not rich so I can't buy the £1000 I'm looking at around £150 But I could make a power supply out of an old pc power supply And just buy a scope

[@CheasingLeaf95]

Nice work!

[@ShawnHymel]

Thanks!

[@dronexfun8469]

I want to test dc motors and lights etc...Is this the type of power supply I should use? thanks a million.

[@shawnhymel7647]

Yes, this type of bench top power supply will work well for testing lights and motors, as you can set the voltage and limit the current.

[@chrisloach9658]

I have an LED light which has a ground wire that I want to test with my power supply.
What should I do with this wire if my power supply only has a positive and negative terminals?

[@constantprayerwarrior]

The ground wire does not need to be connected to ground but you can connect the ground wire to a piece of metal touching the ground

[@rickperez8975]

Where can I learn about DC power supply safety and handling I cannot seem to find any good sources online

[@nsmith0723]

I'm not an expert by any means, but some things to ponder. Keep yourself dry, anything under 24v I personally consider safe in completely dry conditions. Osha says up to 50v should be relatively safe in dry conditions not to say you can get shocked or burned still. You even feel even 9v your tongue. In general mitigate physical contact if you can, ppe like good rubber shoes and gloves might not be a bad idea if your not sure. Again not an expert but I've worked a lot on 12 and 24v systems DC. Currently I'm working with 48v batteries and those I'm going to be using ppe

[@Tardisius]

Bow Ties are Cool =)

[@zongyang779]

Where can i buy one ?

[@SevenDeMagnus]

Cool

[@salsaa24]

what do you call the apparatus with the clips holding the led? where to buy?

[@lathryx]

Hi there, a bit late to this but generally they're called "helping hands" I believe. They're common for soldering components. Hope this helps. :)

[@salsaa24]

Thanks. Actually, timing is perfect 👍

[@salsaa24]

Thanks. Actually, timing is perfect 👍

[@salsaa24]

Thanks. Actually, timing is perfect 👍

[@user-tj1el9uo1m]

where can i find the helping hands please?

[@user-tj1el9uo1m]

Shawn Hymel thanks

[@maheshsrocks]

Can we charge battery?

[@pauluzoma2919]

How can I get the power supply I need it

[@kaylee9069]

Hi all, what is called the device that is holding the resistor at 3:49 ? need to buy one just like that. thanks all.

[@godzillaxtc869]

It’s a Platine holder for Soldering.

[@EasyOne]

nice

[@804MRMAN]

*All this is confusing lol. I have a bench power supply that has 30v and 10 Amp. I just want to test headlight assemblies, but I'm not sure how to set the proper voltage, Amp, what's the difference between coarse or fine.

[@danielmartin3350]

Coarse moves the amperage level up faster (like 1 2 3 4) and the fine knob moves it in smaller increments (1 1.1 1.2 1.3 etc)
This is so if you’re hooked up to a motor let’s say, and you want to hit a specific RPM, you could get it close to speed using coarse and than fine tune the power with the fine knob.

[@cyan6544]

you look like Matt Damon lol

[@timkussmaul1222]

Iam poor :(

[@frankliu1029]

we need subtitles in video

[@sparkfun]

TH-cam offers subtitles on all videos. Turn them on by clicking the CC icon in the settings bordering the video

[@technodruid]

Are you trying to be that guy from Control?

[@paulgrodkowski3412]

Is there any MONEY to be made in this?

[@snorttroll4379]

no. take a look at what people that make money do to make it

[@tutisrihandayani5615]

Name this power supply

[@cfytcf]

Extech 382260

[@pirateman1966]

NEXTECH is shit. Cheap crap. Not even a good price. Pass...

[@nc_yh]

why are you making tutorial when the power supplier isn’t even for sale????? I’m confused

[@gonfreecs1335]

Because most power supply function the same way??

[@Despiser25]

Too much Larping and not enough educating. This was REALLY bad.

[@j5892000]

I finally got one after years lol
