Function

Description

Input protection

Input overcurrent and undervoltage protection is provided.

Output protection

Output overvoltage and short-circuit protection is provided.

Alarm function

Various alarms such as the alarm triggered when there is no power input and the alarm triggered when there is no power output are supported.

Reversed connection protection

-

Overtemperature protection

When the temperature of the power module exceeds a specified threshold (75°C), the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.

Surge protection

-

Hot swapping

Supported

NOTE:

When a power module enters overtemperature protection state, take measures to lower the ambient temperature. The power module can automatically start supplying power again when the temperature falls within the normal range.
