Keithley 2380-500-30 DC Electronic Load – 500V, 30A, GPIB/USB/RS232

The Keithley 2380-500-30 is a programmable DC electronic load for testing and characterizing DC power sources, supplies, and battery systems. Operating from 3.6 V to 500 V at up to 30 A and 750 W maximum power, it delivers four load operating modes—constant current, constant voltage, constant resistance, and constant power—with 0.1 mV / 0.01 mA readback resolution and 0.025% / 0.05% measurement accuracy. Dynamic switching capability reaches 25 kHz with adjustable slew rates, enabling transient response testing and rise/fall time measurement. The instrument incorporates dedicated test modes for battery characterization, LED load simulation, overcurrent/overpower protection validation, and fuse melting time analysis. Comprehensive protection features include over-temperature, over-voltage, over-current, overload, and reverse-voltage safeguards. The single-output load connects via BNC and 9-pin terminal block connectors and accepts analog control from 0 V through 10 V. Memory supports 100 parameter sets for automated test sequences.
