Protection class IP54



Functions and equipments make the VF-S11 universally applicable. The VF-S11 is available up to 4 kW motor as a stand-alone unit with integrated power switch in protection class IP54 / IP 55. Braking unit and line filter are integrated as standard. The exchangeable terminal block allows a manifold integration options with different field bus interfaces. The sensorless vector control with different energy saving controls and automatic slip compensation as well as the high overload capability of the VF-S11 provide for outstanding dynamic and high torque over the entire frequency range up to 500 Hz.
