The KBWM Series of DC Drives are rated for 1/100 to 3/4 horsepower motors and are housed in a NEMA 1 enclosure. These drives are the compact version of the Multi Drive™ (KBMD). This unidirectional SCR drive utilizes the KBMM speed control module, which prevents motor failure due to demagnetization. It requires a Plug-in Horsepower Resistor® to operate and includes an AC line fuse and an Armature fuse holder.* This drive also contains Auto Inhibit® which provides a smooth, safe start during rapid switching of the AC line and a terminal block to facilitate wiring.
