This is an adjustable constant current Electronic Load used for testing of power supplies, DC-DC converters or batteries. Just dial the knob on how much current draw you'd like (from a few milliamps to several amps), and the electronic load will do it's job of dissipating all that Power (Volts x Current) from your PSU under test. A 12VDC power supply is all that is required by the Electronic Load.
Two heavy-duty heatsinks (typically used in computer microprocessors) with integrated cooling fans are used to keep your power MOSFETs cool, allowing you to dissipate anywhere from a few watts to couple hundred watts of power in a very small package.
Constant Current, Adjustable Current Load
Two heavy-duty heatsinks with integrated cooling fans
Two Power MOSFETs operating in parallel
10-turn multi-turn potentiometer for fine-control of the current draw
12VDC operation, wall wart or equivalent
Real-world tested at 60V @ 3Amps (180Watts), 30V @ 6Amps (180Watts), 120V @ 2Amps (240Watts) for 30 minutes duration
Heavy-duty terminals for attaching DUT (Device Under Test)
Read-out of actual load via simple voltmeter, 1mV reading = 1mA current draw
