The Keithley 2380J-500-15 is a programmable DC electronic load for testing and characterizing power sources across multiple operating modes. This instrument delivers constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CP) operation, plus transient modes and specialized LED load simulation for power supply validation. The 500 V, 15 A, 200 W load accepts input from 0.6 V minimum and offers voltage resolution of 0.1 mV with current resolution of 0.01 mA. Measurement speeds reach 50 kHz for voltage and current, while dynamic mode cycling operates to 25 kHz. Adjustable slew rates span 0.0001 A/µs to 2.5 A/µs for precise transient testing.
