Operation manual for the Prodigit 3270 series high‑power AC/DC electronic load.
The Prodigit 3270 series is a high‑power AC/DC electronic load with 16‑bit measurement circuitry, supporting voltage, current, power, harmonic and efficiency measurements. It offers multiple operation modes such as constant current, linear constant current, constant resistance, constant voltage and constant power, and provides GPIB, RS‑232, USB, LAN and I/O interfaces for local and remote control.
The manual covers safety precautions, installation steps, wiring, interface configuration, detailed operation procedures, remote‑control command lists, and application examples such as battery discharge testing, power‑supply OCP/OPP testing, and UPS backup time measurement. This manual is written in Chinese.
