Table 3-10 Functions of a 600 W AC power module
Function Description
Input
protection
Input
undervoltage
protection
In this protection state, the power module stops supplying
power. When the input voltage restores to the normal range,
the power module automatically resumes power supply.
Input
overcurrent
protection
In this protection state, the power module stops supplying
power and cannot automatically resume power supply when
the input current restores to the normal range.
Output
protection
Output
overvoltage
protection
In this protection state, the power module stops supplying
power intermittently. When the system recovers from output
overvoltage, the power module automatically resumes power
supply.
Output
overcurrent
protection
In this protection state, the power module supplies power
intermittently. When the output current is within a range, the
power module automatically resumes power supply.
Output short-
circuit
protection
In this protection state, the power module supplies power
intermittently. When the short circuit is removed, the power
module automatically resumes power supply.
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 swap Supported
NOTE
When a power module enters overtemperature protection state, take measures to lower the ambient
temperature. The power module can automatically resume power supply when the temperature falls within
the normal range.
