The PLZ-4W/4WA Series Electronic Loads are designed for integration in test systems for both characteristic and lifetime tests of a variety of DC power sources, such as switching power supplies, primary/secondary batteries, and Fuel Cell stacks.

The PLZ-4W series have six operation modes: Constant Current (CC), Constant Resistance (CR), Constant Voltage (CV), Constant Power (CP), Constant Current + Constant Voltage (CC+CV) and Constant Resistance + Constant Voltage (CR+CV).

The PLZ-4W/WA Series consists of four models plus a booster unit PLZ2004WB.
To achieve a large capacity system at low cost, the PLZ1004W can be connected in parallel with up to four booster units for a total power of maximum 9kW /1800A. Moreover, up to 5 units of the same model can be connected in parallel in a Master / Slave configuration.

With a high-performance current control circuit incorporated, the PLZ-4W/Wa series provide highly stable, high-speed operation. All models are standard equipped with GPIB, USB and RS232C Interface for esay remote control and system integration.

The PLZ-164WA accepts DC input voltages of 0V, making it ready for characterization of fuel cells.

• 1.5 to 150V
• 66A
• 330W
• Rise time: 10 micro second (which converts to rise and fall times) high-speed response
• Possible to perform actual Load simulation by sequence control function
• Equipped with USB (Supplied as standard)

The Kikusui PLZ334W Electronic Load features faster rise/fall times with variable slew rates for transient testing on high speed DC/DC convertors and DC power supplies. Test modes are constant current, constant resistance, constant voltage, constant power, or a combination of these modes. Current setting resolution can be as low as 20uA. Sequence function permits 10 sequence patterns to be saved in the built in memory. Battery cell discharge times from load on to load off can be measured. Other functions include soft start, short, ABC memory, set up memory, switching. The Kikusui PLZ334W, Electronic Load has GPIB (SCPI compatible), RS232c and USB as standard.
