KB Electronics KBPC-240D PENTA-DRIVE NEMA 4
The KBPC Series NEMA-4X (IP-65) SCR DC Motor Speed and Torque Control is designed for applications requiring washdown watertight integrity. Its housing is ruggedly constructed of die cast aluminum which is protected with an acrylic coating (black 9338) or (white 9342) for the ultimate in corrosion resistance. All switches are sealed with rubber boots and the main speed potentiometer contains a shaft seal.
The KBPC state-of-the-art electronics include short circuit and transient protection to provide the ultimate in reliability. Electronics overload protection is also provided which prevents motor burnout and demagnetization of PM motors. The control can be operated in either the speed or torque mode via a jumper selection. The current range, which is also jumper selectable, eliminates the necessity for calibration of IR compensation and current limit for most applications. The KBPC also contains jumper selections for AC line voltage (230/115), DC armature voltage (180/90) and feedback type (armature/tachometer).
