Altivar 31 Adjustable Speed AC Drives

The Altivar 31 (ATV31) adjustable speed AC drive controller incorporates the latest sensorless flux vector technology into a compact, easy-to-use design for three-phase asynchronous squirrel-cage motors. This versatile drive controller offers increased performance while maintaining cost effectiveness. The ATV31 drive provides advanced speed control capabilities for motors from 0.25-20 hp (0.18 to 15 kW). The controllers range from:

  • 0.25 to 3hp (0.18 to 2.2 kW), 20812301240 V, single-phase input
  • 0.25 to 20 hp (0.18 to 15 kW), 20812301240 V, three-phase input
  • 0.5 to 20 hp (0.37 to 15 kW), 400/480/480 V, three-phase input
  • 1 to 20 hp (0.75 to 15 kW), 52515751600 V, three-phase input

Industrial users and OEMs who specialize in material handling, pump, fan, packing, packaging, and general purpose motor control applications will find the features and functions of the ATV31drive controller well suited for their use.
