The Keithley 2380J-500-30 is a single-output programmable DC electronic load rated for 750 W, designed for dynamic testing of DC power sources, batteries, and power components. Operating across dual voltage ranges—0 V to 50 V (low) and 0 V to 500 V (high)—with corresponding current ranges of 0 A to 3 A and 0 A to 30 A, this instrument delivers voltage readback accuracy of 0.025% and current readback accuracy of 0.05%. The load supports five primary operating modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), Constant Power (CP), and Transient, plus specialized battery and LED simulation modes. Adjustable current rise and fall times span 0.0001 A/µs to 2.5 A/µs, enabling precise transient control. Measurement speed reaches 50 kHz for voltage and current, with dynamic load switching as fast as 25 kHz cycle rate. List mode execution supports up to seven groups of test files with internal and external synchronization. The instrument connects via RS-232, USB, and GPIB for integration into automated test systems. Housed in a 482 mm × 131.4 mm × 533.5 mm rack-mount chassis weighing 24.95 kg, it operates from 100 V to 240 VAC input at 50 Hz or 60 Hz. Minimum operating voltage is 0.36 V at 3 A (low range) and 3.6 V series minimum. Voltage resolution ranges 1 mV to 10 mV with 0.1 mV readback; current resolution is 0.01 mA nominal, 0.1 mA for measurement.
