The KBPB Series of DC Drives consist of two models rated for 1/100 to 3 horsepower motors*. These chassis drives are a compact version of the KBCC “R”control. The APRM® eliminates contact arcing by allowing armature switching to take place only when voltage levels are near zero. Built-in terminal blocks and its small size make the control ideal for installation where space is at a premium. A 5k ohm potentiometer is included. This drive requires a Plug-in Horsepower Resistor® to operate and includes an AC line fuse and an Armature fuse holder.** More Information: Data Sheet, Manual.
