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.

1.2.6 Power conversion
| Input Voltage | Output Power |
| 200Vac～290Vac | 4350W |
| 176Vac～200Vac | Linear derating |
| 176Vac | 4000W |
| 85 Vac～176Vac | Linear derating |
| 85Vac | 1600W |
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
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℃.

1.3.2 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..

| ≤45℃ | The module can output the maximum output power without
over-temperature protection, and the module operates normally |
| 45℃~75℃ | The module power is linearly derated to 2000W |
| >75℃ | Shutdown, self-recovery temperature difference after

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).

< 90%, no condensation) |
| Input to the protected area |

tube, the input lines should be short connected (L&N) together,
and all the output lines should be short connected together.
