Varidigm Corp.: Motor Controllers

The VSM-CP2 and VSM-CP3 variable-speed motor controllers can be used in various air moving applications, including fancoil units, VAV fan terminal boxes, and fan filter units. The VSM-CP2 can be used with standard PSC motors from 1/20 to 3/4 hp, whereas the VSM-CP3 is designed for use with the company’s approved PSC motors. Both controllers are available for 120-V, 240-V, and 277-V, 60-Hz motors. The controllers accept an analog input to provide a pressure setpoint signal, while a pressure sensor provides pressure feedback to the controller, which enables the controller to provide a wider speed range than traditional multi-tap motors, the manufacturer claims.

Varidigm Corp., 3070 Ranchview Lane, Plymouth, MN 55447; 763-258-0170; 763-258-0411 (fax); www.varidigm.com.
