High Efficiency Battery Charger AC DC Converter 150-750V output DC Power Supply 150kw Fast Charging Station Rectifier

Plug technology is applied to the charging module to provide convenience for installation and maintenance The access of the charging module to the system shall not disturb the output voltage of the system

2    Advanced current sharing technology

Under constant voltage working mode the charging modules can share current automatically within 10S with degree of unbalance less than 05A

3    Control of input limited power

Refer to Fig 110 for the relation between the output power and input voltage of the charging module When the input voltage is within 360 Vac  450 Vac return difference is less than 5V the module can output the maximum power of 20 KW when the input voltage is within 260 Vac  320 Vac the module can still work normally under limited power mode

4   Control of output constant power

When there is a rated input voltage the output power of the module is 20 KW Refer to Fig 11 for the relation between the output voltage and the output current of the module

Note

The SD75050 module uses two operating modes with output voltage ranges of 50 to 750V  Boot without a demand voltageThe default operation is in the lowvoltage segment mode if the monitored demand voltage is higher than 600V the module will automatically switch to the highvoltage segment mode When the demand voltage is lower than 550V At the same time it automatically cuts back to the low pressure section mode

The module only selects the operating mode based on the value of the received demand voltage and does not select the operating mode based on the actual output voltage

5    Temperature limited power

Under 55 C ambient temperature the module can output full power of 20kW

Over 55 C ambient temperature the module shall be used by derating with the power Linearly 

Under 65 C ambient temperature the allowable output power of the module is 10kW

Under 75 C ambient temperature the output power of the module is reduced to 0

6    Regulation of output current limiting point

The module has the function of stepless current limiting The current limiting point within the scope of 0333AHigh voltage0A50Alow voltage is adjustable through the external monitoring module When the output voltage is within 50Vdc   750Vdc the current limiting accuracy of the module is 03A

8    Regulation of output voltage

The output voltage of the module can be regulated constantly through the external monitoring module with regulation range of 50Vdc  750Vdc and minimum regulation step of 01 Vdc

9    Fan control

The builtin processor of the module can regulate the speed of the fan according to the internal temperature and output current of the module

10  Protection of input overvoltage voltage shortage

When the input voltage is less than 260 Vac or more than 530 Vac the protection indicator light is on and the module stops working without output

when the module is in Singlephase communication mode the input voltage is less than 160 Vac or more than 300 Vac the protection indicator light is on and the module stops working without output Meanwhile this condition will be transmitted to the monitoring module The function can be recovered automatically

11  Output overvoltage protection

The overvoltage protection point is 260Vdc 770Vdc  10 Vdc Default is 778VdcThe module can be started after manual intervention upon overvoltage protection

12  Overtemperature protection

The environmental overtemperature protection point is 80 C When the DC panel has a temperature over 100 C the module will stop working when the DC panel has a temperature below 90 C the module will automatically work again

13  Protection of internal bus fault

When the internal bus voltage of the module is beyond the overvoltage voltage shortage protection point the module will be powered off automatically At this time there is no output from the module and the fault indicator light is on

14  Short circuit protection

In case of short circuit of the module it will be subjected to protective shutdown and the red indicator light of the panel is on and this condition will be transmitted to the monitor of the module fault

15  Interruption of background communication
