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.

 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 |
