3.1.4.1
AC Inlet Connector
The AC input connector is an IEC 320 C-14 power inlet. This inlet is rated for 10A / 250VAC.
3.1.4.2
AC Input Voltage Specification
The power supply operates within all specified limits over the following input voltage range (see
the following table). The power supply shall power off if the AC input is less than 75-80VAC
ranges. The power supply operates properly starting at 80-85VAC input voltages.
PARAMETER
Voltage (110)
Voltage (220)
Frequency
Notes:
(1) Maximum input current at low input voltage range shall be measured at 90VAC, at max load.
(2) Maximum input current at high input voltage range shall be measured at 180VAC, at max load.
(3) This requirement is not to be used for determining agency input current markings.
3.1.4.3
Efficiency
The 600-W power supply has an efficiency of 68% at maximum load and over the specified AC
voltage.
3.1.4.4
AC Line Dropout / Holdup
An AC line dropout occurs when the AC input drops to zero VAC at any phase of the AC line for
any length of time. During an AC dropout of one cycle or less, the power supply meets dynamic
voltage regulation requirements over the rated load. An AC line dropout of 1 cycle or less (20
ms min) shall not cause any tripping of control signals or protection circuits. If the AC dropout
lasts longer than one cycle, the power supply should recover and meet all turn-on requirements.
The power supply meets the AC dropout requirement over rated AC voltages, frequencies, and
output loading conditions. Any dropout of the AC line does not cause damage to the power
supply.
3.1.4.5
AC Line Fuse
The power supply has one line fused in the single line fuse on the line (hot) wire of the AC input.
The input fuse is a slow blow type. AC inrush current does not cause the AC line fuse to blow
under any conditions. Not all protection circuits shall cause the AC fuse to blow unless a
component in the power supply has failed. This includes DC output load short conditions.
