The compact device is proven in all applications that require both a high acceleration torque and high repeatability. Also for use in rough environmental conditions, the VF-nC3 is the right choice: Coated circuit boards for protection against dust and moisture and permissible ambient temperatures up to 60 °C allow for worldwide, universal use.
Important for export: All models are certified according to the world's important standards and are delivered with manuals in ten languages (on CD). The European model of the VF-nC3 (200 V to 240 V single-phase to 2,2 kW) has integrated radio interference suppression filters for the first environment (residential area) according to the category C1 to IEC61800-3, these can be switched off if necessary. Even under difficult environmental conditions, you can rely on the VF-nC3: All devices tolerate ambient temperatures up to 60 °C, operation up to 3000 m altitude above NN and side-to-side assembly.
The VF-nC3’s energy-saving control system only supplies the motor with the energy it actually needs, thus increasing the efficiency of your drive. Standby shutdown also avoids unnecessary operation – this protects plants and the environment. The VF-nC3 complies with the RoHS Directive, is designed for at least ten years of operation and is recyclable to more than 70 %.
