KBWM
SCR Drive - NEMA 1
The KBWM control is a compact version of the Multi Drive™ (KBMD). The control is packaged in an all-metal NEMA-1 enclosure. This unidirectional SCR drive utilizes the KBMM speed control module, which prevents motor failure due to demagnetization, and contains AC line and armature fusing and a barrier terminal connection block. The KB Plug-In Horsepower Resistor® automatically calibrates IR Comp and CL.
