reduces line harmonics in accordance with the EN61000-3-2 and JEIDA MITI standards.
reduces line harmonics in accordance with the EN61000-3-2 and JEIDA MITI standards.
5.1.4.1
AC Inlet Connector
The AC input connector is an IEC* 320 C14 power inlet. This inlet is rated for 15A / 250VAC.
5.1.4.2
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±5VAC
ranges. The power supply operates properly starting at 80-85VAC input voltages.

Maximum input current at low input voltage range shall be measured at 90VAC, at maximum load.
2
Maximum input current at high input voltage range shall be measured at 180VAC, at maximum load.

5.1.4.3 Efficiency
The 670W power supply has an efficiency of 68% at maximum load and over the specified AC
voltage.

AC Line Dropout / Holdup
An AC line dropout occurs when the AC input drops to 0VAC 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 minimum) 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.
