The LV-VFD is a heavy duty VFD for continuous operation and designed as LV-SVFD for short time starting operation.
Drive starter applications:
- Starting of standard asynchronous and synchronous motors.
- Retrofit to any existing induction- and wound rotor motor.
The VFD guarantee smooth continuous speed control and step-less acceleration without any mechanical shock to the motor and the load (if used as SVFD drive starter until full speed and the by-pass is closed).
