Inrush current
The power supply must meet inrush requirements for any rated AC volt-
age, during turn on at any phase of AC voltage, during a single cycle AC
dropout condition, during repetitive ON/OFF cycling of AC, and over the
specified temperature rang. The peak inrush current shall be less than the
ratings of its critical components (including input fuse, bulk rectifiers, and
surge limiting device).
Line fuse
Each PSU is supplied with a fast blow type fuse in the live line input wire.
It protects PSU from the short circuit inside of it.

In case a line fuse is blown up, please check internal components
of the PM for damages or contact the developer.
