The FV20 series frequency transformer is a versatile industrial device designed for precise control of motor speed and torque. These compact, energy-efficient units feature robust construction for harsh environments, offering adjustable output frequencies typically ranging from 0-400Hz. Common applications include conveyor systems, pumps, fans, and CNC machinery, where they provide smooth acceleration/deceleration and process optimization. The series supports multiple control modes (V/F, sensorless vector) and includes protective functions against overloads, short circuits, and phase loss.
