The Kikusui PLZ603W is a 600W DC electronic load engineered for rigorous testing of power supplies, batteries, and power distribution systems. Operating across 1.5V to 120V DC input with current capability up to 120A, it delivers four independent operating modes—constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CP)—enabling diverse test scenarios from transient simulation to steady-state characterization. The PLZ-3W Series architecture emphasizes CPU-controlled stability and speed, with CC mode response time of 50µS and fastest Tr/Tf settings in CC/CR modes also at 50µS.
