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.
| KEY FEATURES | |
| Operation Voltage | 0.25 V to 150 V |
| High Speed Slew Rate | 60 A/μs |
| Arbitrary I-V Characteristics | "ARB Mode Included |
| Parallel Operation Feature | Total current and power can be increased to a maximum of 10.8 kW (2160 A) with booster units |
| Various Communication Interfaces | LAN (LXI Compliant) USB RS232C GPIB (Option) External Analog Control |
| BENEFITS | |
| Color Liquid Crystal Display (LCD) | Highly resolution color display allows for the convenient monitoring of values such as voltage, current, power, current capacity (Ah) and power capacity (Wh) all in the same place. |
| New Numeric Keypad for easy Operation | Values can now be input directly from the front panel. |
| Industry’s Highest Slew Rate of 540 A/μs | Achieves a rated current (*2160 A) rise time of 4 μs. Supports high-speed transient response testing, which is becoming increasingly significant for power supply evaluation. The slew rate increases proportionally to the number of units operating in parallel. Maximum slew rate of 60 A/μs can be set for the single PLZ1205W (rated current: 240 A). |
| High Speed Voltage Tracking Characteristics | High speed voltage tracking in CR mode is perfect for applications such as power supply startup tests. |
