Impressive miniature power supply
Heatsink was loose. I unplugged upper board and removed two screws holding the heatsink. The heatsink presses against 2 transistors and a diode pack. There was no thermal paste. I applied thermal paste and also added a #4 split washer and flat washer for the central heatsink screw. I still gave 5* because this is amazing tech for the price. No-Load current across Vin range is on the order of 20mA when OFF, 40mA when ON. Control settings are a bit finicky and hard to figure out, but do work. When turned ON, the output rises with a time constant of about 100ms. There are separate settings for CC and OCP. CC limits the current, while OCP turns OFF the output.

Does not suck! I even accidentally reversed input polarity, and works
A handy little power supply, and great for an LED system Im setting up. For anyone that wants to print a case, I have an STL and OpenSCAD file for the supply with a fan and mount for aluminum extrusion. Fan and binding posts that I use are also from MPJA. Can email me at mcinsand at gmail.
