3.3 Input Ratings (480VAC, with 486532603 Rectifier)
3.3.1 Voltage: Nominal 480 volts AC, three phase, 60 Hz, with an operating range of 340 to 528
volts. Acceptable input frequency range is 57 to 63 Hz.
3.3.2 Harmonic Content: Complies with IEEE-519-1992. Voltage harmonic distortion of less than
5% at nominal input when operating on a line impedance of 0.104 ohms or less.
3.3.3 Inrush Current: Peak does not exceed 6 times the RMS input current at full load, under any
conditions of input voltage within the rated input voltage range stated in Paragraph 3.3.1 and
for any duration of AC input interrupts. Under the above conditions, standard AC distribution
circuit breakers will not trip.
3.3.4 Typical Input Data: 60 Hz input.
(A) System output is initially adjusted to 54.48 volts DC as measured at the output bus at 50%
of full load and nominal input.
