DESCRIPTION
The KBCC chassis control utilizes the KBMM™ modular
control to provide a low-cost, reliable, variable speed SCR
drive for PM and Shunt Wound DC motors. Models with
the “R” suffix contain the KB APRM
®
* which provides
anti-plug “instant” reverse and solid state dynamic
braking. 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 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 KBCC controls are built on a rugged aluminum
heatsink and contain AC line and armature fusing, a 5K
ohm remote potentiometer, and a barrier terminal block.
In lieu of the potentiometer, the control can be operated in
a voltage following mode by supplying an isolated analog
signal (0-9VDC) to the input terminals P2 (+) and F-.
Adjustment trimpots are provided for MIN, MAX, IR COMP,
CL, ACCEL and DECEL.
* Patented.
