The KB Electronics KBMD-240D Multi-Drive from HMA Flow & Industrial is a packaged SCR drive in a NEMA-1 enclosure. It utilises the KBMM speed control for its electronics. The Multi-Drive is rugged and compact in size. It handles both 115 and 230 V AC line inputs by setting the built-in dual voltage switch. In addition, this single model can be used on a wide range of motor horsepower by simply inserting the appropriate plug-in horsepower resistor. The optional auxiliary heat sink optional increases the rating of the basic unit. An optional forward-brake-reverse switch kit is also available.
