Schneider Electric Canada has introduced Simply Smart industrial ac drives for 3-phase asynchronous motors from 0.5 to 900 hp. The Altivar 71 model, dedicated to all industrial applications, is complemented by the Altivar 61, for pumps and fans. Altivar 71 can deliver up to 220% overtorque; 130% for Altivar 61. Both drives offer flux vector control (FVC) with or without sensor, online auto-tuning, speed or torque control, output frequency up to 1000 Hz and an energy saving function for pump and fan applications. One drive can independently control up to 3 motors, units withstand voltage drops of up to -50%, RF interference and operating temperatures up to 50ºC (without derating).
