MR483000HG2B-GS Rectifier Module of Telecom Power System
MR483000HG2B-GS is a power supply device that converts standard AC voltage into stable 48Vdc for
communication power supply system.
For a larger load capacity, the rectifier modules can be connected in parallel, or an additional independent monitoring module can be used for intelligent control.
The rectifier module is a plug-in modular unit designed to be compatible with racks and cabinets.

Description of the indicator lights of the rectifier module of Telecom Power System
| Indicator | Indicator color | Status | Status description | Suggested solution |
Power indicator | Green | On | Module AC input is normal | Normal state, no action required |
Off | The AC input of the module is abnormal (no input power supply, input power supply over-voltage and under-voltage, etc.) | Check whether the input is normal; if the input is normal, replace the rectifier module | ||
4Hz flashing (4times/sec) | Manual query status | Normal state, no action required | ||
Alarm indicator | Yellow | Off | No abnormal alarm | Normal state, no action required |
On | Temperature pre-alarm (ambient temperature exceeds 65℃ ~ over-temperature shutdown) | Check whether the ventilation of module are blocked and whether the ambient temperature is normal | ||
Dormancy shutdown (when the module is in dormancy shutdown, only the protection indicator is on, and the module does not report an alarm) | Normal state, no action required | |||
290Vac<Input voltage<300Vac | Check if the input voltage is normal | |||
| Module current limiting | Normal state, no action required | |||
4Hz flashing (4times/sec) | Module hardware address error | Check if module is inserted in place and locked | ||
0.5Hz flashing (1times/2s) | The communication between the module and the outside is interrupted | Replace the rectifier module or monitoring module; check the CAN bus wiring of the power system for errors | ||
Fault indicator | Red | Off | No abnormal alarm | Normal state, no action required |
On | The output is locked due to over-voltage or the module is not inserted in place | Unplug the rectifier module, wait for more than 1 minute, and then insert it | ||
| No output caused by internal fault of rectifier module | Replace the rectifier module |
