The power supply meets UL enclosure requirements for temperature rise limits. All sides of the
power supply, with exception of the air exhaust side, are classified as “Handle, knobs, grips,
etc., held for short periods of time only.” You must pay special attention to the fan case
temperature; it cannot be exceeded under any conditions.
2.2.1.4 LED Marking and Identification
The LED is green or amber when lit
.
2.2.2 AC Input Requirements
The 600-W power supply incorporates a universal power input with active power factor
correction, which reduces line harmonics in accordance with the EN61000-3-2 and JEIDA MITI
standards.
2.2.2.1 AC Inlet Connector
The AC input connector is an IEC 320 C-14 power inlet. This inlet is rated for 10A/250VAC.
2.2.2.2 Efficiency
The following table provides the required minimum efficiency level at four loading conditions:
100%, 50%, 20% and 10%. Efficiency is tested at the AC input voltage 230VAC.

2.2.2.3 AC Input Voltage Specification
The power supply operates within all specified limits over the following input voltage range, as
shown in the following table. Harmonic distortion of up to 10% of rated AC input voltage will not
cause the power supply to go out of specified limits. The power supply powers off at or below
75 VAC +/-5 VAC range. The power supply starts up at or above 85 VAC +/-4VAC. Application
of an input voltage below 85 VAC does not cause damage to the power supply, including a fuse
blow.
