Kerry Wong built this DIY dummy load in a hard drive cooler aluminum case: Basic constant current dummy load using an Op Amp and a by-passing MOSFET is very easy to build and had been made quite popular following Dave’s video … Read more
Nick designed re:load, a cheap 0-30A general purpose dummy load and posted it in the forum a few months ago. It’s got over-current, over-voltage, and over-temperature protection. While the circuit is similar to many other DIY dummy loads out there, … Read more
Nickjohnson posted his flexible dummy load project in the project log forum: I’ve been testing Loki’s power supply lately, and hurting for the lack of a good dummy load. There are plenty of flexible dummy load projects out there, but they’re … Read more
Another review of ITead’s OverLoad programmable dummy load: All in all, interesting device. The only major flaw I see attm is that instead of using DAC and drive the current value trough mcu they are doing that analogue … I’ll … Read more
Another constant current dummy load. This one is capable of up to 10amps at 40volts. Since I’m planning to build two bench power supplies, I needed to build a current load to test them. So, I’m going to show you … Read more
Schematic and source for ITead’s programmable dummy load are now available.
The computer controlled power supply being developed in the forum is progressing nicely. We got a big boost when Fenugrec posted a few circuit simulations based on a common commercial power supply typology. The simulated circuit is now available as … Read more
We really enjoyed Dave’s video about a junk box constant current load. It can be used to test a number of things like battery capacity, heat sink characteristics. Via Hackaday.
