KBMD-240D KB ELECTRONICS 11AMP NEMA1 SCR SPEED CONTROL BI-DIRECTION 9371

Multi Directional (Forward-Brake-Reverse) packaged drive in a NEMA-1 enclosure. It utilizes the KBMM™ speed control for its electronics. It handles both 115 and 230VAC line inputs by setting the built-in Dual Voltage Switch. In addition, the single model can be used on a wide range of motor horsepower by inserting the appropriate Plug-in Horsepower Resistor®. The Auxiliary Heatsink (optional) increases the rating of the basic unit.

KBMD Multi-Drive™ represents the latest in state-of-the-art design for variable speed DC motor controls. It is rugged and compact is size and is able to handle both 115 and 230V AC line inputs by setting the built-in Dual Voltage Switch. In addition, the single model can be used on a wide range of motors by selecting and inserting the appropriate Plug-in Horsepower Resistor®.
The standard model, KBMD-240D, controls all motors through 3⁄4 Hp at 115V and 1.5 Hp at 230V. By installing the KB Auxiliary Heatsink, the horsepower range is increased to 1 Hp at 115V and 2 Hp at 230V. The versatility of the control is enhanced with a Forward-Brake-Reverse Switch Kit installed.
The electronics for the Multi-Drive™ consists of KB’s patented KBMM™ speed control module. Its field-proven reliability is confirmed by over 100,000 controls presently in operation. The KBMM™ module is housed in a rugged metal (not plastic, like other inexpensive drives) enclosure. Keyhole slots facilitate mounting while a readily accessible terminal block simplifies wiring. Included with each control is a detailed instruction and user manual.

IMPORTANT: Rating indicated is with Auxiliary Heatsink (P/N KB9861) . Maximum rating without Auxiliary Heatsink is 1/2 Hp at 115V and 1 Hp at 230V. * Performance is for 90V PM motors on 115 VAC and 180V PM motors on 230 VAC.
