NOTE: You are buying a bare PCB (Printed Circuit Board) only. Some assembly required. Parts/Components not included. PCB Only.

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

Review: Hi, Just finished assembling the FFA e-Load and it is everything I had hoped for! It is very stable and easy to use. The current sense tracks very well which was a pleasant surprise. I would have found lesser performance to be quite acceptable especially for such an inexpensive device, but this gem functions much better than merely acceptable! A very good design overall. I couldn’t be more pleased! Please feel free to quote me in your reviews if you wish. Thank you so much, Jerry Thiel
