Output Voltage	Remark
+53.5V	long - term short circuit is allowed,  automatic recovery is triggered when short circuit fault disappears

1.3.2 Output Over-voltage Protection

Output over voltage protection can be divided into the internal over voltage protection and the external counterpart. Internal overvoltage fault range is 58.5VDC~60.5 VDC, which can be set through monitoring; when failure occurs, the module is locked. The external voltage is greater than 63VDC and lasts more than 500ms, the module is locked. Being in the protection state, the AC power supply shall be disconnected first and then reenergized to ensure the power supply resumes work properly.

1.3.3 Output Under-voltage Alarm

The input under-voltage range is 37VDC~39VDC. When the input voltage is lower than the under-voltage alarm value, alarm prompt will be reported with normal output.

420±5V dc	Output is off and the input is disconnected from the power grid. Output can be recovered automatically when the voltage is normal.

>75℃	The module recovers automatically with the temperature hystersis>10℃ in the state of shutdown when the temperature is above 75℃

1.4 Communication between Rectifier Module & Monitoring Module 

CAN-bus communication mode is adopted between the rectifier module and the monitoring module. Remote software version upgrade is supported, and the address of the module can be set through the address board. When AC input is disconnected, the module needs to communicate with the host.

Isolation design is employed for CAN interface in the rectifier module. The power supply of CAN is +5Vdc, which is provided by the rectifier module internally.

The main monitoring information of the rectifier module is as below:

1) Voltage regulation & current regulation functions: meeting the requirements of floating charging battery and voltage regulation;

2) Single module control of startup & shutdown;

3) Protection & Alarm Information Feedback:

Mains fault: mains fault (AC input over-voltage/under-voltage);

Module protection: temperature pre-alarm;

Module fault: fan fault, over temperature shutdown or no output caused by the module internally;(the module is in the state of dormancy and shutdown, and the mains failure is not reported to the module).

1.5 LED Indicator

LED indicators are installed on the side board with details as below:

 

Indicator	Color of Indicator	Normal State	Abnormal State	Root Reason
running indicator	Green	On	Off	Mains power failure (no AC input, AC input over-voltage/under-voltage), no output of the module.
protection indicator	Yellow	Off	On	Temperature  Pre-alarm (ambient temperature over 65°C ~ thermal shutdown) Dormancy shutdown (when dormancy shutdown, only the protection indicator light is on without any alarm). Communication interruption (protection indicator flickers)
malfunction lndicator	Red	Off	On	Output over-voltage shutdown, fan failure, over-temperature shutdown, no output caused by the module internally.

2. Insulating Property

Output-PE	effective value or equivalent DC voltage 710Vdc 1minute ≤30mA

Note: when the lightning protection device is added in the circuit, the discharge gap tube shall be disconected during the Hi-pot test before the following operations are carried out: all the input lines (L&N) shall be short connected, and it applies to all the output lines.
