Multifunctional Electronic Load PLZ-5W Series

High-speed response, universal interface, large-scale system compatibility

The PLZ-5W series electronic load is the successor of the highly respected PLZ-4W that continues the series tradition of high
specification and excellent build quality.
New improvements include a user-friendly LCD color display and a wide voltage range from 0.25 V to 150 V. Custom voltage/current profiles can now be programmed using the new ARB function, ideal for LED driver and solar panel testing. The PLZ-5W now includes 6 basic modes of operation (CC, CR, CV, CP, CC+CV, & CR+CV) for optimal flexibility in any test facility.
The PLZ-5W is now equipped with a high-speed response feature boasting a maximum slew rate of 60 A/us (PLZ1205W) and a minimum setting resolution of 10 uA (PLZ205W).
 
Additional features include a soft-start function, variable slew rate, selectable response mode (CV/CR mode), switching function, ABC programmable memory, 20 user-defined setup configurations, and a sequence function. The high-speed response of the PLZ-5W is ideal for the development and testing of modern day power supplies that require sudden changes in current at high speeds as well as for testing of current clamps and transducers. The PLZ-5W series is available in 4 standard models which can be incrementally expanded by adding booster units (PLZ2405W) for a maximum of 10.8 kW/2160 A. The PLZ-5W now is equipped with a diverse digital communication interface supporting LAN (LXI), USB, RS232C, analog control, and GPIB as a factory option.
