Intelligent control for safe and
reliable charging

Protection function

• 

  Input overvoltage and undervoltage protectionInput overvoltage and undervoltage protection

  When the three-phase AC input voltage range isless than 269±3V or greater than 540±3V,the module will stop working.

• 

  Input phase loss protection

  Three-phase AC input if a phase is missing, the module will stop working.

• 

  Output overvoltage protection

  The output overvoltage protection point is 1025±5V, After the module software triggers the overvoltage protection, the shutdown automatically restarts.

• 

  Output short-circuit protection

  If the module is in short-circuit state for 3 consecutivetimes within 100±10ms, the module will be locked and stop, and it needs to be powered off to resume normal operation. Other states are short-circuited, the module can stop to protect, and then the module will work normal.

• 

  Internal over-temperature protection of the module

  When the internal device temperature of the module is higher than 55°C, linear derating begins based on the current limit value, and when the device temperature reaches 65°C, the derating is reduced to 50% and when the temperature is higher than 75°C, the module shuts down.

• 

  Fan fault protection

  When the fan fails for about 3s, the module LED display board displays the fan fault code, and the module stops. After the delay is about 5s, the module tries to resume normal operation. If the fault persists, the module stops again, such as the second loop.

Smaller size to support higher power
and higher efficiency output

Take a 480kW charging system as an example:

• High efficiency of 40kW module
• Less heat to be dissipated
• Easier to design the cooling system
