Description
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 adapter does not have fans. The heat dissipation is
provided by the fan module of the device.
Hot swap
Not Supported.
