Drive selection memo — 11 kW constant or variable torque
The Delta VFD110B23A is a VFD-B series AC motor drive rated for 11 kW (15 HP) on a 3-phase 220 V supply, delivering 49 A output from 0.1 to 400 Hz. That output current covers most 11 kW four-pole induction motors at full load; if your motor nameplate says 48 A or less at 230 V, this drive lands right on the rating. The 0~240 V output range means it handles both 208 V and 230/240 V motor windings without a transformer — common on North American and Asian 220 V class lines. The VFD-B series is Delta's general-purpose platform, so expect standard V/f, sensorless vector, and torque control modes, though the evidence doesn't detail which control scheme is preloaded.
