This user manual introduces the panel operation, technical specifications, installation, and communication interface reference of the IT8500 series DC programmable electronic load from Edex Electronics (Nanjing) Co., Ltd. The product features various operating modes such as constant current, constant resistance, constant voltage, and constant power. It supports dynamic testing operations in continuous mode, pulse mode, and trigger mode, as well as sequential operation and triggered operation. Furthermore, the product has protection functions for overvoltage, overcurrent, over power, and over temperature, as well as remote testing, access control, and battery discharge testing.
The IT8500 series is a single‑input programmable DC electronic load with RS‑232 communication, a high‑visibility VFD display, and multiple protection features. It supports constant current (CC), constant voltage (CV), constant resistance (CR), constant power (CW), pulse, continuous, trigger and list operation modes, as well as remote and battery testing functions.
The manual provides a quick‑start guide, detailed panel operation instructions, installation steps, safety warnings, technical specifications, application examples, and communication interface references for RS‑232, USB and GPIB connections. This manual is written in Chinese.
| Input voltage options | 110 V or 220 V |
|---|---|
| Fuse specifications (220 V) | T0.5 A 250 V |
| Rise speed | 0.5 A/µs |
| Memory capacity | 25 groups |
When the load is powered on, a system self‑test runs for about one second; if EEPROM or calibration data are missing, the VFD displays error messages.
Remove the small plastic cover under the rear power socket with a flat‑head screwdriver, locate the fuse, and replace it with one matching the specified rating.
