Description of ➡️ QEBIDUM LM2596S DC-DC Buck Converter: Step-Down Regulator Power Module with LED Voltmeter Display

LM2596 Buck Converter Module with voltage display function, the displayed accuracy is ± 0.05V, range is 0 - 40V.( Note: in order to voltage display more accurate, please ensure that the input voltage is higher than 4V). LED digital voltmeter tube, the accuracy is adjustable function, can be aimed at your multimeter adjustable accurate. Press the right key to let the display show the input or output voltage. when the right “OUT” led light, it shows output, the left “IN” led show input. Continuously adjustable output voltage range of 1.25V -37V, 4-40V input voltage range.(The input voltage is at least high than the output voltage of 1.5V). Output current: 2 A continuous output. Output power: the maximum 15 w. ensured 3A output load current, current limit protection, and thermal shutdown.

Looks good for power converter

Nice little thing. It might work but I don't know because there were no instructions. Thank god for the internet. I bought this for my 3D printer to install a laser kit but ended up exploding my motherboard. live and learn

Pros
  • Alright!
Cons
  • Not everything fits

Cheap Chinese imitation or original, just poor quality

Mine arrived with a loud high frequency hum/hum that only got worse with more current during use and fluctuating voltage, which made them for the rendered useless for the most part. I had to return them for a refund.

Pros
  • Very good value for money
Cons
  • Has flaws

Doesn't provide a stable power supply

This device is little better than a resistor with a voltage display. It reduces the input voltage from anywhere between 1.2 to 2.5 volts, but does not maintain a stable output voltage and simply reduces the input voltage to the output voltage at a constant ratio, somewhat adjustable with an adjustment potentiometer.

Pros
  • An absolute legend
Cons
  • Some little things

Does exactly what it says. Exactly.

I bought this to step down 12v to 5v. At first I didn't get 5V out. I always read 12V no matter what I did. Apparently it defaults to pull down 24V to 12V so you have to turn the potentiometer a few times before the voltage starts to drop. Once it started dropping I set it to 5V and tested it with my multimeter. The output voltage was +-0.01V, which is within the tolerance I needed.

Pros
  • GOLS certified
Cons
  • Not the best

I WIN! Made it possible for my robot to use a large battery,

I connected a 32v Jumper Mighty Jump car battery to the frame of my Arduino robot tank. Your product allowed me to drop the voltage from 32V down to 11.1V, giving my robot a 40 minute run time compared to 10 minutes that the other 11.1V battery gave me. Just know, when the battery starts putting out less volts, its output voltage also goes down. Make sure the power adapter is fully charged before setting the output

Pros
  • weight
Cons
  • disappears
