Input protection

Input undervoltage protection

In this protection state, the power module is turned off and stops supplying power. When the system recovers from input undervoltage, the power module can automatically start supplying power again.

Input overcurrent protection

In this protection state, the power module is turned off and stops supplying power. The power module cannot automatically start supplying power again and needs to be replaced.

Output protection

Output overvoltage protection

In this protection state:

• If output overvoltage is caused by the power module itself, the power module stops supplying power. When the system recovers from output overvoltage, the power module cannot automatically start supplying power again.
• If output overvoltage is caused by increase of the input voltage received from the external power source, the power module stops supplying power. When the system recovers from output overvoltage, the power module can automatically start supplying power again.

Output overcurrent protection

In this protection state, the output current is limited to a certain value. When the system recovers from output overcurrent, the power module can automatically start supplying power again.

Output short-circuit protection

In this protection state, the power module supplies power intermittently, and the output current is limited to a range. When the system recovers from output short-circuit, the power module can automatically start supplying power again.

Overtemperature protection

When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.

Hot swapping

The power module is hot swappable.

FAULT

Red

Steady on: The power module has a fault that cannot be rectified.

ALM

Yellow

Steady on: A power output shutdown alarm, overtemperature alarm, output overcurrent alarm, input overvoltage alarm, or input undervoltage alarm has been generated.

Blinking: Communication with the monitoring device (MCU or CMU) has been interrupted.

RUN

Green

Steady on: The power input is normal.
