The Kikusui PLZ72W is a DC electronic load instrument designed for testing and validation of power sources, batteries, and DC output devices. Operating from 0 V to 60 V and drawing up to 120 A at 720 W maximum power, it delivers three independent operating modes—Constant Current, Constant Voltage, and Constant Resistance—with fine control resolution and fast transient response. Built-in protection circuits guard against overcurrent, overvoltage, over-temperature, and reverse input conditions.
