Variable Speed DC Motor Control

The KBIC® full-wave DC motor speed controls are designed for applications demanding excellent performance, high reliability and low cost. Although compact in size (only 4.30" x 3.64" x 1.25"), these controls offer better than 2% regulation over a 50:1 speed range. The controls are fabricated with components which have proven reliability, including MOV transient protection, which is used to protect the power bridge. Integrated circuitry is used to provide a non-complicated design with superior load and line voltage regulation. Electronic current limiting (CL) protects the motor and control against overloads by limiting the maximum level of output current. Acceleration start (adjustable from .5 to 4 seconds) provides a smooth start each time the AC power is applied.
