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. The KBPB is equipped with a built-in dynamic brake resistor, ACCEL and DECEL trimpots, and includes a
5k ohm potentiometer. This control provides functions identical to that of the KBCC-R. This drive 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
