back to variable loads

150w programmable load with USB:




I bought one of these awhile ago and found out (the hard way) that when it says 150 watts, it means 150 watts.
Not 200, not 160, not even 152. 150. I let the magic smoke out by turning the knob a little too far and
just barely passing 150 watts as the power mosfet went crispy and stinky.

So I bought another one. (and eventually got a replacement mosfet and repaired the original) These are pretty
versatile units, with a variety of inputs on them and an independent wall-wart for powering the tester without
drawing power from the load. It has inputs for USB-A, USB-mini, USB-micro, USB-C, 5.5mm barrel, and wire lugs.
Its only down-side is that 150 watts can be pretty limiting.
