KB Electronics 9428 DC SCR Chassis Speed Control, 230 VAC, KBIC-240, 6 Amps

Description

Description
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. The Inhibit™ circuit (terminals I1 and I2) is provided to electronically disconnect the armature output voltage. Another standard feature is Auto Inhibit®. This circuit prevents false starts and high surge currents when cycling the KBIC® control with the AC line.
A variety of models are provided with choices of voltage and current ratings. Model KBIC-240D operates on both 115 and 230 VAC to provide 0 – 90 and 180 VDC output. Model KBIC-240DS operates on both 115 and 230 VAC to provide 0 – 90 VDC output. Included with the controls are a 5K remote potentiometer, mounting hardware and operating instructions.
