Zhiyu ZBP30A1 Electronic Dummy Load

Posted on November 6, 2016 The Engineer

Here’s a useful tool for testing both power supplies & batteries, a dummy load. This unit is rated up to 60W, at voltages from 1v to 25v, current from 200mA to 9.99A. This device requires a 12v DC power source separate from the load itself, to power the logic circuitry.
