Power switch
The power switch allows you to turn on or off the power
output.
STATUS indicator
(green/red)
l
Steady green: The output of the DC power module is
normal.
l
Steady red: The output of the DC power module is
abnormal or in protection state (except hiccup mode
protection state, in which the indicator blinks).
Power cable terminal
Connect the black wire to the RTN (+) terminal and the blue
wire to the NEG (-) terminal.

Item
Description
Input undervoltage
protection
Stops power output and automatically restores power output
after the input voltage becomes normal.
Input overvoltage
protection
Stops power output and automatically restores power output
after the input voltage becomes normal.
Input overcurrent
protection
Stops power output and does not automatically restore power
output after the input current becomes normal.
Output current limiting
protection
Intermittently provides output and automatically restores
normal output after the output current falls within a normal
range.
Output overvoltage
protection
Intermittently stops output and automatically restores output
after the overvoltage condition is removed.
Output short circuit
protection
Intermittently provides output and automatically restores
normal output after the output short circuit is removed.
Overtemperature
protection
When the temperature of the power module reaches a preset
threshold, the power module stops power output and will
automatically restore power output after the temperature drops
back to the normal range.
Heat dissipation
The power module does not have fans. The heat dissipation is
provided by the fan module of the device.
Hot swap
The device has 1+1 power module redundancy. You can hot-
swap a power module without interrupting device operation.
