Thanks to Direct Torque Control (DTC) technology, the ACS 600 SingleDrive performs precise speed and torque control of standard squirrel cage motors, without the added cost and inconvenience of pulse encoder feedback.
The range includes models to suit most applications, with a selection of voltage, power, enclosure ratings and communications capabilities.
- power range from 2,2 kW to 3000 kW
- supply voltages from 380 V to 690 V
- enclosure classes IP 00, IP 21, IP 22, IP 42 and IP 54
