The Kikusui PLZ164WL is a high-speed DC electronic load engineered for testing power supplies, batteries, and energy storage systems across a wide range of operating conditions. This unit combines compact form-factor capability with 165W maximum power handling and operates from 0.3V to 30V with full-load current delivery of 100A at 0.3V. Six independent operating modes—Constant Current (CC), Constant Resistance (CR), Constant Voltage (CV), Constant Power (CP), and two hybrid modes (CC+CV and CR+CV)—enable precise characterization of source behavior under dynamic load profiles.
