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
specied temperature rang. The peak inrush current shall be less than the
ratings of its critical components (including input fuse, bulk rectiers, 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.
Line fuse is resistant to starting current or inner protection circuits.
In case a line fuse is blown up, please check internal components
of the PM for damages or contact the developer.
Eciency
Power Supply Unit is certied with an 80 Plus Platinum level certicate
of ecient energy use. Maximum eciency reaches 94% at 220 Vin
