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.

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 | ||
