The Keithley 2380-120-60 is a programmable DC electronic load engineered for precision characterization of DC power sources, DC-DC converters, batteries, and power distribution systems. Operating from 1.8 V to 120 V at up to 60 A, this 250 W benchtop instrument delivers high-resolution voltage and current measurements alongside four operating modes—constant current, constant voltage, constant resistance, and constant power—making it suitable for both laboratory development and production test environments.
