PLZ-4W Series Multifunctional DC Electronic Load (CC/CV/CR/CP/Zero volt input) : 6 Models
The PLZ-4W Series Electronic Load unit is a multifunctional system designed to offer the highest levels of reliability and safety with operation function of constant voltage, constant current, constant power and constant resistance mode. And its control unit comes with GPIB, RS232C and USB as standard equipment, available in 5 models.
A 0(Zero)V input operating voltage is available in 2 models (PLZ164WA, PLZ664WA) which are suitable to meet the testing demands for the Fuel Cell, DC/DC converter, SW Power Supply, and any other devices required for the lower operating voltage application. Model PLZ664WA offers the 132A at 0V input as a largest current rating in its class. ( 33A for model PLZ164WA)
Furthermore, the PLZ-4W features high speed slew rate when switching, it can be used as simulating load for the characteristic, performance, life cycle, aging test in the field of application in Automobile electronics, SW Power Supply manufacturer, Secondary Battery.
To achieve large capacity for testing application at low cost, PLZ1004W can be expanded up to 9kW by using its 2kW booster unit (PLZ2004WB).
- High-speed response and variable slew-rate
With PLZ-4W series, a faster response of rise/fall time as calculated conversion value with 10 µs is made possible, enabling a transient response test for the direct current and accurate reproduction of a simulation waveform as a dummy load. In addition, it also can be set with a slew rate (A/µs ). As for the setting value, it can be varied continuously, and be possible to optimize transient control for voltage drops due to wiring inductance, constant-voltage power supply, etc., when the load current is switched on.
