See Page 8. 4 KBPB SCR Drive “Relay Reversing” – Chassis 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.
