4 Hardware Overview
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.
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 heat dissipation is provided by the
fan of the power module.
The device has 1+1 power module
redundancy. You can hot-swap a
power module without interrupting
device operation.
