PSU Load for testing
Posted: 01 Mar 2020 19:43
Just a little something I knocked up for running PSU's with a load that isn't an ST.
It's made using the load resistors from exxos' store, an old low profile PC heatsink, a 6 pin plug and a bit of veroboard.
First step was to solder up the 5 pin plug onto the veroboard, then the resistors soldered to a common ground on one end that fed back up the veroboard to the plug, ground and the other ends to the 5v and 12v sides of the 6 pin plug respectively.
Then a spot of thermal paste on top of the heatsink and resistors, and sandwich it all up good and tight. Gets quite warm, but good for testing and adjusting without worrying about damaging your ST.
