380Vac to 110VDC 20A rectifier module

RM11020-B2 is a power supply device that converts 3phase 380V AC voltage into stable 110Vdc 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.

1.3  Remote On/Off Control：(Remote control function - 485 communication)

1、Remote signaling

Transmit the module's protection signals (AC overvoltage, undervoltage, phase loss, overtemperature, output overvoltage, overcurrent, etc.) and fault signals to the monitoring unit.

2、Remote monitoring

Monitor the module's output voltage and current and report to the monitoring unit.

3、Remote control

Control the module's ON/OFF state and switch between boost and float charge according to the monitoring unit's commands.

4、Remote adjustment

Adjust the module's output voltage and set the output current limit within the range of 10% to 100% based on the monitoring unit's commands.

 1.4  Protection:

1.4.1 Table 9 DC output Over Voltage Protection.

Note: In the event of an open-loop fault, the output overvoltage protection point does not exceed 155V.

1.4.2 Table 10 DC Output Short Circuit Protection.

1.4.3 Table 11 AC Input Over voltage Protection.
