Over voltage protection can be divided into internal and external overvoltage protection. The internal overvoltage fault range is 58.5VDC~ 60.5VDC, which can be set by monitoring. In case of failure, the module locks. If the external voltage is greater than 63VDC and lasts more than 500ms, the module is locked. After entering the lock machine protection state, it is necessary to disconnect the AC power first, and then power on again, so that the power can work again.

1.4 Communication function between rectifier module and monitoring module

The CAN bus communication mode is adopted between the rectifier module and the monitoring module, which supports the remote software version upgrade, and the module's address CAN be set through the

address board.

After the communication between the rectifier module and the monitoring is interrupted for 1 minute, the rectifier module starts up and the output voltage and current limit values return to the default values.

The CAN interface in the rectifier module needs to be designed in isolation. The power supply of CAN is + 5VDC, which is provided inside the rectifier module.

The main monitoring information of rectifier module is as follows:

1) Voltage regulation and current regulation function: to meet the floating charging requirements of the battery and to meet the voltage regulation requirements;

2) Single module switch machine control;

3) Protection and alarm information feedback:

Utility fault: Utility fault (AC input over voltage);

Module protection: temperature warning;

Module failure: no output caused by over-voltage shutdown, fan failure, over-temperature shutdown or other internal reasons of the module;

(The module is in hibernation and shutdown state, and the mains power failure is not reported to the module fault).
