The Keithley 2380-500-15 is a programmable DC electronic load rated for 500 V and 15 A operation across a 200 W power envelope. This single-output instrument provides four fundamental operating modes—Constant Current, Constant Voltage, Constant Resistance, and Constant Power—plus transient capabilities for dynamic testing of power supplies, DC/DC modules, LED drivers, and battery systems. The load delivers voltage readback resolution to 0.1 mV and current readback resolution to 0.01 mA, with measurement speeds reaching 50 kHz and dynamic cycling up to 25 kHz. Programmable current rise/fall times range from 0.0001 A/µs to 2.5 A/µs.
