Table 6-2 describes the functions of a 150 W AC power module.

Table 6-2 Functions of a 150 W AC power module



Input protection

Input undervoltage and overvoltage protection is provided.

Output protection

Output undervoltage, overvoltage, overcurrent, and short-circuit protection is provided.

Overtemperature protection

When the temperature of the power module exceeds a specified threshold (70°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


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.
