DC motor speed controller KB Electronics
3 hp (2.25 kW)

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. A unique feature of the KBIC® controls is the Plug-in Horsepower Resistor®. It eliminates the need for recalibrating IR Comp and Current Limit when the control is used on various horsepower motors. Additional versatility is achieved by using the Auxiliary Heatsink (optional) which is used to double the horsepower rating of each model. The output of the control is a linear function of potentiometer rotation. The KBIC® can also be operated in a voltage following mode by supplying an isolated analog signal (0 – 9VDC) to the input terminals P2 (+) and F-. The controls are terminated as standard with Q-D terminals. A Barrier Terminal Accessory Kit is available which incorporates both line and armature fuses.
