Variable Speed Drive Panels (Variable Torque)

Nema 3R 10hp VSD

A variable speed drive (VSD) is required for applications needing programmable motor running speed. VSD panels are complete motor control packages used in applications requiring a disconnecting means, starting circuitry, VSD and motor overload protection. These VSD panels are medium duty (Variable Torque) configurations.

In the standard configuration, these drive panels are intended for use indoors. If your application requires a main disconnect, please see our disconnect page or consider the bypass option. Please call us with your special environmental considerations. We can configure a VSD panel to fit almost any environmental conditions.

Can Line and Load Reactors save your VFD & increase the life of your motor?


New Utility Transformers allow higher available Fault Currents. When advised, we can provide controls with proper interrupting ratings. Short Circuits may cause welding, which is not considered a failure of the Contactor. (see UL508, Para 53)
