The KB Electronics KBPB "cycler" control is designed to provide antiplug "instant" reversing, solid state dynamic braking and rapid cycling. It combines all of the features of the KBMM speed control with the features of the KB APRM. Contact arcing is eliminated since the APRM allows armature switching to take place only when current levels are near zero. The KBPB contains a built-in barrier terminal block and its compact size makes the control ideal for installation where space is at a premium.
All models are equipped with KB's exclusive Plug-in Horsepower Resistor. It eliminates the need for recalibrating IR Comp and Current Limit when the control is used on various horsepower motors. The basic ratings of the controls are enhanced with the addition of KB's Auxiliary Heatsink. The controls also contain Inhibit, which allows for electronic switching of the armature voltage, and Auto Inhibit, which provides rapid, safe switching of the AC line.
The controls can be used to drive all PM and Shunt Wound DC motors from 0-full speed by three separate methods: a 5K remote speed pot, an auxiliary speed pot (S4 terminal), or voltage following. If the control is to be operated in a voltage following mode, an isolated analog signal (0-9VDC) is applied to the input terminals P2 (+) and F (-). Adjustment trimpots are provided for MIN, MAX, IR COMP, CL, ACCEL and DECEL.
