Table 6-78 describes the functions of a 1000 W DC power module.

Table 6-78 Functions of a 1000 W DC power module



Input protection

Provides protection against input overvoltage, input undervoltage, and input overcurrent.

Output protection

Provides protection against output overvoltage, output overcurrent, and output short circuits.

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


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.

Table 6-79 describes the indicator on a 1000 W DC power module.

Table 6-79 Description of the indicator on a 1000 W DC power module






  • Off: The power input is abnormal (for example, no input, overvoltage, or undervoltage) or the power output is abnormal (for example, overvoltage or overtemperature).
  • Steady on: The power module is working normally.
