re:load a cheap 0-3A general purpose dummy load
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, the key to Nick’s safer solution is the usage of the BTS117 smart low side switch IC, which acts as a regular N-channel MOSFET, but has all of the above mentioned protection circuitry built in. This project is now available on Tindie.DIY, project logs and tagged BTS117, DIY, dummy load.
