First look: RuiDeng DPS 50v 5 amp adjustable buck power supply

These are hugely popular, and cheap buck adjustable power supplies.

They claim 250w output, but they are tiny!

I wanted to run a quick test to see how they handled a little bit of that power.

Using my trusty electronic load (rated to 150w) I dialed up as much power as my bench top power supply could muster.

How hot do you think it got?

At ~90w the electronic load was up at 100+ degrees C.

The DPS5005 was hardly hot at all!

Looking at it from the top, the components were

Less than 50 degrees C.

I’ll have to wait until I have a better power supply to do a proper load test. But so far, I’m impressed!
