The output voltage of the module can be regulated constantly through the external monitoring module, with regulation range of 50Vdc ~ 750Vdc and minimum regulation step of 0.1 Vdc.
9. Fan control
The built-in processor of the module can regulate the speed of the fan according to the internal temperature and output current of the module.
10. Protection of input overvoltage/ voltage shortage
11. Output overvoltage protection
The overvoltage protection point is 260Vdc ~770Vdc (�±10 Vdc). Default is 778Vdc.The module can be started after manual intervention upon overvoltage protection.
12. Over-temperature protection
The environmental over-temperature protection point is 80�°C. When the DC panel has a temperature over 100�°C, the module will stop working; when the DC panel has a temperature below 90�°C, the module will automatically work again.
13. Protection of internal bus fault
When the internal bus voltage of the module is beyond the overvoltage/ voltage shortage protection point, the module will be powered off automatically. At this time, there is no output from the module and the fault indicator light is on.
14. Short circuit protection
In case of short circuit of the module, it will be subjected to protective shutdown and the red indicator light of the panel is on, and this condition will be transmitted to the monitor of the "module fault".
