Product Details
1. Cable connection
The input/output wiring is fixed with bolts to improve the seismic resistance of on-board transportation.
The Can communication line adopts socket assembly, and it is recommended to fix it with glue after debugging.
2. Input power limiting control
The relationship between the output power of the charging module and the input voltage. When the input voltage is between 220Vac and 280Vac (with a return difference of less than 5V), the module can output
Output power 7KW; When the input voltage is between 90Vac and 220Vac, the module can still operate normally but is in power limiting mode.
3. Output constant power control
At the rated input voltage, the allowable output power of the module is 7KW, and the relationship between the module output voltage and output current
Description: This module adopts two working modes:
1) The module receives monitoring instructions and operates in either 32A mode or 16A mode (with different power limiting points).
2) Output 50V~500V and 500~750V in two sections. In the absence of required voltage, the startup defaults to working in the low-voltage section mode, and when the module actually outputs high
At 525V, the module automatically switches to the high-voltage section for operation. When the demand voltage is below 500V, it automatically switches back to the low-voltage section mode for operation. When the module output goes from high
When the pressure changes towards low pressure, there will be a brief drop in the output of the module across the switching point; When the module output changes from low voltage to high voltage and crosses the switching point, the module output
No drop phenomenon, power output when crossing switching points.
4. Temperature limiting power
Under an ambient temperature of 55 ℃, the module outputs 7kW at full power;
Derating for use above 55 ℃ ambient temperature is a segmented linear power limiting;
At an ambient temperature of 65 ℃, the module allows for an output power of 3.5kW or greater.
At an ambient temperature of 75 ℃, the output power of the module decreases to 0.
5. Output current limiting point adjustment
The module has stepless current limiting function. The current limiting point of the module can be adjusted within the range of 0-20A through external monitoring modules. When the output voltage is between 50Vdc and 750Vdc
The current limiting accuracy of the module is ± 0.3A.
6. Output voltage regulation
Through an external monitoring module, the output voltage of the module can be continuously adjusted, with an adjustment range of 50Vdc to 750Vdc and a small adjustment step of 0.1Vdc.
7. Fan control
The built-in processor of the module can adjust the fan speed based on the internal temperature of the module and the output current of the module.
8. Input over/under voltage protection
The module input is a single-phase AC voltage. When the input voltage is below 90Vac or greater than 280Vac, the module will stop working and have no output.
When an overvoltage or undervoltage alarm occurs, the module will report the alarm information to the monitoring module; When the input voltage returns to the normal range, the alarm disappears and the module returns to normal
Return to normal working condition.

9. Output overvoltage protection
After overvoltage protection, manual intervention is required before starting the machine.
The software overvoltage protection point can be set through the monitoring module, with a setting range of 76Vdc to 778Vdc, and the factory default value is 778Vdc.
Manual intervention: The module can be reset through the monitoring module, or it can be reset by powering on again after AC power outage.
10. Over temperature protection
The protection point for environmental overheating is 80 ℃.
When the temperature of the DC board exceeds 85 ℃, the module stops working; When the temperature of the DC board drops below 75 ℃, the module will automatically resume operation.
11. Internal busbar fault protection
When the internal bus voltage of the module exceeds the overvoltage/undervoltage protection point, the module will automatically shut down, and there is no output from the module at this time.
12. Short circuit protection
When the module is short circuited, protect the shutdown and report "module fault" to the monitoring.
13. Background communication interruption
The module experiences a communication interruption for more than 20 seconds. The module is shut down for protection and there is no voltage output. After communication is restored, it is necessary to resend the power on command before starting up.
14. Fan fault protection
When a fan fails, the module will generate a fan fault alarm, and the module will shut down without voltage output. After the fault is eliminated, the module will automatically resume operation.
15. Monitoring Performance
The charging module adopts CAN bus.
The installation steps for the charging module are as follows:
1. Install the hanging ears on the corresponding positions of the chassis according to the installation method of the cabinet.
2. Slowly push the charging module fully into its slot or secure it to the installation board.
3. Tighten the fixing screws on the charging module ear and secure it to the cabinet. The ear fixing screws are M4, with a recommended torque of 12kgf.cm
4. When installing cables, cables should be larger than 6 square meters or AWG10 # wires, and terminals should be OT6-4. It is recommended to have a torque of 14kgf.cm
