4.2 AC Input Ratings
4.2.1 Voltage: Nominal 208 volts AC, three phase, 50/60 Hz, with an operating range of 176 to 264
volts. Acceptable input frequency range is 45 to 65 Hz.
Maximum non-destructive input voltage when rectifier is not operating: 600 VAC
4.2.2 Current: <18A @ 5800 W, and at an input voltage of 176 VAC.
4.2.3 THD (Total Harmonic Distortion): ≤5% when loaded at 50 to 100% of the rated output power.
4.2.4 Inrush Current: <150% of the rated input steady-state peak value.
4.2.5 Typical Input Data: 60 Hz input.
(A) System output is initially adjusted to 54.48 volts DC as measured at the system sense points
at 50% of full load and nominal input.
