DESCRIPTION
The KBMM™
1
full-wave, variable speed, DC motor
control offers the user the ultimate in reliability and
performance at an affordable price. The control
contains a unique, superfast, Direct-Fed™ current limit
circuit that helps to protect the SCR power bridge
against direct shorts
2
. The reliability of the KBMM™ is
further enhanced with the use of high-surge, 25A
SCR’s and line and armature fusing
3
. The KBMM™ is
fitted with KB’s exclusive Plug-in Horsepower
Resistor
®
3
. It eliminates the need for recalibrating IR
Comp and Current Limit when the control is used on
various horsepower motors. In addition, the rating of
the control can be extended to 1
1
⁄2 Hp at 115V and 3
Hp at 230V by the use of KB’s auxiliary heatsink.
The versatility of the KBMM™ is confirmed by its
extensive list of standard features, such as: selectable
armature or tach feedback and adjustment trimpots for
min speed, max speed, IR comp, CL and linear Accel
and Decel. The circuitry of the KBMM™ includes Auto
Inhibit
®
, which eliminates surging during rapid AC line
switching; pulse transformer triggering, which provides
cogless operation at low speed under no-load conditions;
and superior noise rejection circuitry, which eliminates
false starts and blown SCR’s.
The output voltage of the control is a linear function
of potentiometer rotation. In addition, the control can
be used in a voltage following mode by supplying an
isolated analog input signal to terminal P2+ and F-.
The KBMM™ is compact in size (only 4.3" x 3.64" x 1.25")
and easily replaces all competitive speed controls.The
control is supplied with a 5K remote potentiometer and
full operating instructions.
