RM22020-B2 is a power supply device that converts 3phase 380V AC voltage into stable 220Vdc 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：

1、Telecommunication

Transmit the protection signals (AC over-under-voltage, phase loss, over-temperature, output over-voltage, over-current and other signals) and fault signals of the module to the monitoring unit.

2、Telemetry

Measure the output voltage and current of the module and report to the monitoring unit.

3、Remote control

According to the command of the monitoring unit, control the ON/OFF of the charging module, both float charging conversion.

4、Remote control

Adjust the output voltage of the module according to the command of the monitoring unit, and adjust the current limit point of the output power within the range of 10% to 100%.

1.4  Protection:

1.4.1 Table 9 DC output Over Voltage Protection.

Note: If the power system enters a faulty open loop state, the output overvoltage protection point does not exceed 330V
