MR483000HG2B-GS 48V 3000W High Efficiency Rectifier Module Hot Swappable Wide Input Range 85 290VAC
MR483000HG2B-GS 48V 3000W High Efficiency Rectifier Module Hot Swappable Wide Input Range 85 290VAC
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.

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 |
