5A Adjustable Digital DC Load
« on: May 30, 2024, 08:54:49 am »
A DC load is an essential testing tool for any electronic enthusiast, especially for testing and repairing power supplies. An adjustable DC load can limit the current at any desired level, which makes it suitable to perform various tests because some problems of the feedback loop are only detectable by variable load tests. Also for any SMPS repair attempt, the output should be tested against some loads, not just voltage stability, because the problem might lie within the current sensing on the primary side (a common problem of Flyback SMPSs).

The schematic and PCB have been designed using Altium Designer 24 and the Gerber files are provided to download from the Altium-365 cloud space. You can power the board using your mobile phone USB Type-C charger; no external power supply is necessary.
