Function

Table 5-2 describes the functions of a 60 W AC power module.

Table 5-2  Functions of a 60 W AC power module

Function

Description

Input protection

Provides protection against input undervoltage condition.

Output protection

Provides protection against output undervoltage, output overvoltage, output overcurrent, and output short circuit conditions.

Overtemperature protection

When the temperature of the power module exceeds a specified threshold (70°C or 158°F), 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 temperature of the power module. The power module can automatically start supplying power again when the temperature falls within the normal range.
