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 85 VAC does not cause damage to the power supply, including a
blown fuse.

Maximum input current at low input voltage range is measured at 90 VAC, at max load.
Maximum input current at high input voltage range is measured at 180 VAC, at max load.
This requirement is not to be used for determining agency input current markings.
3.3.3
AC Line Isolation Requirements
The power supply meets all safety agency requirements for dielectric strength. Transformer isolation
between primary and secondary windings must comply with the 3000 VAC (4242 VDC) dielectric strength
criteria. If the working voltage between primary and secondary dictates a higher dielectric strength test
voltage the highest test voltage should be used. In addition, the insulation system must comply with
reinforced insulation per safety standard IEC 950. Separation between the primary and secondary circuits,
and primary to ground circuits, must comply with the IEC 950 spacing requirements.
3.3.4
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
