NOTE 1: See Section 3.0 for model number breakdown.
NOTE 2: The first current ratings listed are for 120 Vac input, the second current ratings are for 208 Vac input,
and the third current ratings are for 240 Vac input. 120 Vac input yields three phase 230 Vac output.
NOTE 6: STD = standard unit; THRU = through-hole mount unit. Values are worst-case (not typical) for 6kHz
carrier frequency at full speed and full load.
