KBMM – Variable Speed DC Motor Controls

Products Description
The KMM™ full-wave, variable speed, DC motor control offers the user the ultimate in reliability and performance at an affordable price. The control contains a unique, superfast, direct-fed™ current limit circuit that helps to protect the SCR power bridge against direct shorts. The reliability of the KBMM™ is further enhanced with the use of high-surge, 25A SCR’s and line armature fusing. The KBMM™ is fitted with KB’s exclusive plug-in horsepower resistor. It eliminates the need for recalibrating IR comp and current limit when the control is used on various horsepower motors.
