2U 24Vdc 60A telecom rectifier module

  • RM2460-A

  • NASN

  • RM2460-A

Availability:

RM2460-A is a power supply device that converts standard AC voltage into stable 24Vdc 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.

1.2.10 Rectifier module and monitor module communication function  

RS485 communication mode (half-duplex, double-line) is adopted between the rectifier module and the monitoring module.

The RS485 interface in the rectifier module needs to be isolated. The RS485 power supply is +5Vdc (regulation accuracy ±5%), which is provided by the monitoring module.

The main monitoring information of the rectifier module is:

1) Adjust Voltage and Current function: meet the requirements of battery floating charge and meet the adjust voltage requirements;

2) Single module switch machine control;

3) Alarm information:

Mains failure: mains failure (AC input over voltage);

Module protection: temperature pre-alarm;

Module failure: Output over voltage shutdown, fan failure, over temperature shutdown or no output caused by internal causes of other modules; (module is in: sleep shutdown state, mains failure does not report module failure).
