looks really solid! will buy again.
Tested out fine. output range at 12v in was about 34.6v no load. I would call that well within spec. Voltage adjustment potentiometer has pretty nice precision, it is not hard to dial into a voltage, nice and fine adjustment. I did not test the constant current function, i am sure it is ok too. Did not measure output ripple, but it should be ok. voltage output shows stable on meter to .001 so if there is an issue where i need a smoother signal, i will just run it though a linear regulator. Very good value for the price.
