| Overvoltage protection output |
Enable O.V.P protection in the menu. The protection threshold can be set arbitrarily. The output will be turned off when protection is activated. |
| Overcurrent protection output |
Set the menu to O.I.P protection. The protection value can be customized. After protection, the output is disabled. |
| Overtemperature Protection |
Built-in O.T.P protection with a protection threshold of 85°C ±5% (radiator temperature). |
| Voltage Setting |
Menu settings, encoder knob input |
| Current Setting |
Menu settings, encoder knob input |
| Communication mode |
RS-485/RS-232 (supports Modbus and SCPI protocols) |
| Function |
Constant voltage/constant current, return-type current protection, memory mode, LIST sequence cycle, adjustable ON/OFF time, pulse width output, 9999 cycles, three preset voltage current settings (full-width models), button lock |
| Output polarity |
The positive (+) and negative (-) outputs can be grounded arbitrarily. |
| Heat dissipation method |
Air blast cooling |
| Operational environment |
Indoor interior design specifications: Temperature: 0°C to 40°C; Humidity: 10% to 85% RH |
| Storage Environment |
Temperature: -20°C to 70°C; Humidity: 10% to 90% RH |
| Note: All values are typical and may exceed these figures under different loads or other conditions. The accuracy is measured during load-side voltage detection; deviations between actual and rated values may occur due to temperature errors and component aging. |
| Note: FS stands for full scale range; the three digits indicate the last displayed value. |
