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

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

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

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.

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.

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.
