Description
The power switch allows you to turn on or off the power
output.
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).
Connect the black wire to the RTN (+) terminal and the blue
wire to the NEG (-) terminal.
The serial number that uniquely identifies the power module.
lists the functions of the 350 W DC power module.
Description
Stops power output and automatically restores power output
after the input voltage becomes normal.
Stops power output and automatically restores power output
after the input voltage becomes normal.
Stops power output and does not automatically restore power
output after the input current becomes normal.
Intermittently provides output and automatically restores
normal output after the output current falls within a normal
range.
Intermittently stops output and automatically restores output
after the overvoltage condition is removed.
Intermittently provides output and automatically restores
normal output after the output short circuit is removed.
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.
The power module does not have fans. The heat dissipation is
provided by the fan module of the device.
The device has 1+1 power module redundancy. You can hot-
swap a power module without interrupting device operation.
