1. Electrical specifications

1.1 Input characteristics

Note: 1. The minimum starter voltage is less than 95VAC.

1.2 Output characteristics

1.2.1 Output voltage and current adjustment rate

Note: The output current regulation and communication interruption of the rectifier module are as follows:

1) The output current of the rectifier module can be adjusted according to the current command. The adjustment range is 1A~81.3A.

2) If the communication between the rectifier module and the monitoring module is interrupted for more than 1 minute, the output of the rectifier module will automatically return to 53.5V and the state of

unlimited flow.

1.2.2 Output ripple and noise

Note: 1) Ripple and noise test: Ripple and noise bandwidth set at 20 MHz.

1.2.3 Output dynamic response

Note: load jump cycle 4ms.

1.2.4 Output overshoot

Note: Load range during test: minimum to maximum.

1.2.5 Startup output delay time

Note: Start-up delay time is the time from AC power on to output voltage to 42VDC.

1.2.6 Power conversion

The output 53.5~58V is based on the upper limit power, and the output 42~53.5V is based on the external characteristics and the proportional power limit

The above is a curve that limits the maximum output power according to the input voltage; all are

theoretical limit values, and the actual limit will have a certain deviation due to the input voltage accuracy (±2V), output voltage accuracy (±0.6%) and output current accuracy (0.8A) ; The voltage error of the power conversion point is <±2V.

1.2.7 Output characteristic

Remarks: The above are the theoretical limit values, the actual limit will have a certain deviation due to the current accuracy (current error <±0.8A) .

1.2.7 Startup output delay time

Note: Start-up delay time is the time from AC power on to output voltage to 42

1.2.8 Over-temperature drop curve

Note:

The input is greater than 200Vac, the output 53.5~58V is based on the upper limit power, and the output 42~53.5V is based on the external characteristics and the ratio of the power limit;

The input is less than 200Vac, and the output 53.5~58V is limited in proportion to the input power limit; the output 42~53.5V is limited in proportion to the external characteristics and the input power limit.

The above are the theoretical limit values, and the actual limit will have a certain deviation due to ambient temperature accuracy (±2°), input voltage accuracy (±2V), output voltage accuracy (±0.6%) and output current accuracy (0.8A); The ambient temperature error of the rated point is less than ±2℃.

1.2.9 Noise voltage

1.3 Protection function

1.3.1 Output short circuit protection

1.3.2 Output overvoltage protection

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.

1.3.3 Output undervoltage warning

The range is 37VDC~39VDC. When it is lower than the undervoltage alarm value, it will output normally and report an alarm..

1.3.4 Input overvoltage protection

Note: Input overvoltage protection shall be tested at 75A rated load.

1.3.5 Input undervoltage protection

1.3.6 Over temperature protection

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).

1.5 LED

The power supply LED indicator is installed on the side of the power panel. The output state is shown in the table below.

2. Insulation performance

2.1 Insulation Impedance

2.2 Resistant to high voltage

Note: if the circuit has lightning protection device, the voltage test should be performed after the opening of the electrical gap tube, the input lines should be short connected (L&N) together, and all the output lines should be short connected together.

3. Safety standards

Power supply safety meets the following standards:

GB4943

IEC/EN60950 IEC/EN62368-1

Power supply safety certification:

CE certification (LVD and EMC directive requirements)
