3.2.2 Current: <13A @ 5800 W, and at an input voltage of 260 VAC.
3.2.3 THD (Total Harmonic Distortion): ≤5% when loaded at 50 to 100% of the rated output power.
3.2.4 Inrush Current: <150% of the rated input steady-state peak value.
3.2.5 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.
