. For any single or three phase voltage from 208 V to 575 V, the Amperes Input at Rated Load Output is the same for 50 Hertz or 60 Hertz input
power. For example, the amperes input for 230 V, 50 Hz, single-phase input power is 33 amperes. The amperes input for 230 V, 60 Hz, single-phase
input power is also 33 amperes.
