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.

1.
The maximum input current at low input voltage range is measured at 90VAC, at max load.
2.
The maximum input current at high input voltage range is measured at 180VAC, at max load.
3.
This requirement is not to be used for determining agency input current markings.
4.6.3
AC Line Isolation Requirements
The power supply meets all safety agency requirements for dielectric strength. Transformers' isolation
between primary and secondary windings complies with the 3000VAC (4242VDC) dielectric strength criteria.
If the working voltage between primary and secondary dictates a higher dielectric strength test voltage, the
highest test voltage will be used. In addition the insulation system complies with reinforced insulation per
safety standard IEC 950. Separation between the primary and secondary circuits, and primary to ground
circuits, complies with the IEC 950 spacing requirements.
4.6.4
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 will recover and meet 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.
