3.5 AC Input Requirement
The power supply shall incorporate universal power input with active power factor correction
which shall reduce line harmonics in accordance with the EN61000-3-2 and JEIDA MITI
standards.
3.5.1 AC Inlet Connector
The AC input connector shall be an IEC 320 C-14 power inlet. This inlet is rated for
15A/250VAC.
3.5.2 AC Input Voltage Specification
The power supply must operate within all specified limits over the following input voltage
range, shown in below table. Harmonic distortion of up to 10% of rated AC Input Voltage
must not cause the power supply to go out of specified limits. The power supply shall power
off on or after/below 75Vac ±5Vac range. The power supply shall start up on or before/above
85VAC ±4Vac. Application of an input voltage below 85VAC shall not cause damage to the
power supply, including a fuse blow.

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.
4. Maximum rated input current is measured at 100VAC and 200VAC
3.5.3 Power Factor Correction
The power supply shall incorporate a Power Factor Correction circuit. The power supply shall
be tested as described in EN 61000-3-2: Electromagnetic Compatibility (EMC) Part 3: Limits-
Section 2: Limits for harmonic current emissions, and shall meet the harmonic current
emissions limits specified for ITE equipment. The power supply shall be tested as described
in JEIDA MITI Guideline for Suppression of High Harmonics in Appliances and General-Use
Equipment and shall meet the harmonic current emissions limits specified for ITE equipment.
