Thanks for posting. I thought mine were not adjusting correctly... but with your video, I found out you just have to keep turning and turning and turning and then it will adjust. Much appreciated.

Ty for this video. Leaving a comment that may be helpful to others... If you try to reduce the voltage and nothimg occurs, just keep spinning that little selector using a small tool... After 5 or 6 turns you will note the voltage to start to decrease until the led turn off... By that moment you should read around 1.25 v in your multimeter using the 20vcc scale. Now you are able to spin the selector to the oposite direction and select your voltage requirements (sorry for my english, not native)

I only watch these vids for the bangin' choons, wicked!

Can I use a 3.7v lipo batterie on the input and adjust the output to 6v

[VARocketry]

I guess watching videos, even as good as yours and others, doesn't ensure success or even an adequate understanding ...
I'm trying to find a battery power source to power four strobe light units installed on my PARAMOTOR as we fly in often congested airspace.  Air Force and civilian aircraft like to fly low over the water just off the beach here in Northern Florida just where we'd like to fly.
I purchased supposedly 12v truck led strobe light KIT to attach to my frame.  I finally got a multimeter this week and measured the demo battery pack that comes in the strobe package (allows strobes to work on the store shelves) and - the batteries were providing 19.5 vdc.   


So these are likely the fairly standard 12-24v LED strobe lights sold everywhere.
I have a spare 6S LiPo 50C battery pack that provides 22-25.5 vdc so I figured I use this.  My plan was to wire up the LM2596 to measure the output voltage and adjust the potentiometer to 19-20 vDC output to test the strobe lights.  Input measured 25.1vDC.I put the multimeter leads on the OUT side and made a short piece of twin lead wire connect the IN side and inserted them into the XT60 connector.


BOOM
A firecracker went off and the capacitor was gone. I turned the Multimeter on after I inserted the twin wire, don't know if that caused the overload - no load when connected?


The video said the LM2596 was rated for 30 vDC.  A flying buddy offered that perhaps the 6S LiPo's amperage was too much.

I measured the 6S LiPo and it jumped around but seemed to be between 373 and 420 mA.  It's a new Chinese multimeter and I probably don't know how to use it properly.


The small battery pack seemed to measure between 95 -200 mA when connected and would drop to ZERO when the button was pushed.  Not sure I understand that behavior.  

Any comments you'd care to offer to me.  I have another spare buck to use but need to figure some other combination to power the strobe lights.

*Bro mere paas same module tha lekin mujh uske use ke baare me is video se information mili thanks make more DIY Using this module..*

[neelranade]

I have used this module to simple 7805 power bank circuit and lm386 audio amplifier and given input 3v battery pack and the module don't work? What can I do? Please help

[digialarm]

Very helpful, thanks. I also thought I had faulty units. The pots I'm familiar with dont have unlimited travel like these units. Good video

[STECK]

Can I use this as 12v lead acid battery charger ?
& What is the current carrying capacity of this module ?

[blakdeth]

Thank you for showing how this works. I was turning the screw on the potentiometer the wrong way so the voltage was not changing and I was getting frustrated. #usererror Haha

[srirajletchimanan]

Hello, can we connect the LM2596 with external digital potentiometer?

[xadion]

i have an AC-DC laptop adapter that gives 30volt, can i use this to make it give lower volts to use the adapter to my phone?

[yusufkasimch]

Is it work as a voltage limiter? I mean if input voltage fluctuates from 15v to 20v can it give constant 5v output?

[Prince_KC]

What happens if out voltage is set to 12v & if input voltage fluctuates from 14v - 12v. Will output voltage also fluctuates?

[GotScout]

Can I place these in a sealed box from elements or will they overheat?

[aqibakbar]

im commectimg this to 12v power supply, it goes to max but it doesnt give output below 12v
any reason why?
thankyou

[CREATORX]

where you got those clipper wires for your multimeter

[DugmerJunction]

Hi, Any idea how I would connect this with an IR sensor and LED strip light? Sensor has 3 pins and LED standard two

[lekno]

Sip sip.. adjust ke kiri .menurunkan tegangan yah.. rek.utk 12 v .kalau utk 24 v bagus juga kah.??

[darshitmathur]

Hello sir! Can we use this module to charge 12.6v lithium ion battery pack ?
