more than expected

Reviewer: from Edmond Oklahoma

I ordered the model without the voltage readout (cheaper) but All sent me the more expensive model. I like to think maybe they were out of stock and were kind enough to substitute. This model does have some neat bells and whistles. It actually has two modes of operation, selectable by an on-board push button. Two SMT LED's let you know which mode it is in. In one mode ti seems to read out the incoming voltage. In the other mode the precision pot is used to set the output voltage. In both modes the voltage is accurately displayed on the readout. Strangely, I was only able to get this unit to boost voltage up, never down. I was working off 12v and perhaps from a higher voltage it works differently.

NIIIICE little regulator

Reviewer: from York, PA

Used this on a modified New Bright Hummer, using a 12V 4AH SLA battery. Set the regulator for 9.9 volts, runs 9.7-9.8 when running. Slight power drop when going from 0 to full throttle fast, but it does keep up fairly well. To get lower voltage you must crank the screw out several turns before it sees it - but it does drop below 12V.

Just what I needed

Reviewer: from UT USA

I plugged this in, adjusted the voltage (I was getting 19v DC and I dialed it down to 12v DC). It was fast, it was easy and it worked like a charm. I'll be ordering more of these for sure.

Useful regulator

Reviewer: from Maryland

Nice buck regulator board. Module looks well made. Output >2A with a 12V input. It does get quite warm at 2A. Should be useful as an general purpose bench supply. Screw terminals are small, so don't over-tighten the screws. Short-circuit protection did work. Read the LM2596 data sheet at
