General Information

- The KB Electronics KBIC-240 full-wave DC motor speed control is 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

- A unique feature of the KBIC-240 control is the Plug-in Horsepower Resistor® which eliminates the need for recalibrating IR Comp and Current Limit when the control is used on various horsepower motors

Standard Features

- Plug-in Horsepower Resistor® allows a single model to be used on a wide range of motors
- MOV Transient Protection
- Trimpots: MIN, MAX, ACCEL, IR & CL
- Voltage Following
- Inhibit™ and Auto Inhibit®
- Dual Voltage Capable on 230V “D” and “DS” Models

Typical Applications

- Conveyors
- Packaging Machines
- Feeders
- Welding Positioners
- Pumps
- Machine Tools
- Exercise Equipment
- Screening and Printing Equipment
