2.1.4.2 AC Inlet Connector
The AC input connector is an IEC 320 C-14 power inlet. This inlet is rated for 10A/250VAC.
2.1.4.3 AC Input Voltage Specification
The power supply operates within all specified limits over the following input voltage range.
Harmonic distortion of up to 10% of the rated line voltage does not cause the power supply to
go out of specified limits. Application of an input voltage below 85VAC does not cause damage
to the power supply, including a blown fuse.

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.
2.1.4.4 AC Line Dropout/Holdup
An AC line dropout is defined to be when the AC input drops to 0VAC at any phase of the AC
line for any length of time. During an AC dropout the power supply meets dynamic voltage
regulation requirements. An AC line dropout of any duration does not cause tripping of control
signals or protection circuits. If the AC dropout lasts longer than the holdup time the power
supply recovers and meets all turn on requirements. The power supply meets the AC dropout
requirement over rated AC voltages and frequencies. A dropout of the AC line for any duration
does not cause damage to the power supply.
