Re:load: A simple, flexible adjustable dummy load

Re:load is an adjustable constant current load with the following properties: No external power supply required – powered by the device under test Wide range of input voltages, from 3.3 volts to 32 volts Adjustable load from 0 to 3.5 amps Up to 14 watts power dissipation (with design heatsink) Virtually indestructable: The power FET, BTS117, has built in overtemp, ESD, and overcurrent protection Load remains constant under different input voltages – 40 milliamp variation over input voltage range Screw terminal and banana plug footprints Low BoM cost, and easy to solder thru-hole parts Test points for reading current with a voltmeter A simple, flexible adjustable dummy load – [ Link ] DIY Constant Current Dummy Load Simple analog programmable load Programmable dummy load ELV Dummy Load for Power Supply Testing Another OverLoad review
