AC Inverter HF320a

Sumitomo HF320α AC Micro Drives are similar to the SF320 AC drive series with the addition of a sensorless vector control mode.

Sensorless vector control produces higher starting torque and offers a wider constant torque speed range. HF320α AC drives are available from 1/4 to 10 HP, 200-240V and 1/2 to 10 HP, 380-480V and are suitable for 50Hz or 60 Hz operation.
