DESCRIPTION
The KBMM™ full-wave variable speed DC motor controls, now with SMT
construction
, offer the user the ultimate in reliability and performance at an
affordable price. The controls contain a unique, super fast, 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 SCRs and AC line and armature fusing
5
. The KBMM™ is fitted with KB’s
exclusive Plug-in Horsepower Resistor®
5
. 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 heat sink. Models KBMM-
225 and KBMM-225D also allow operation of 90 VDC motors when used on
230 VAC line input.
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
KBMM™ includes Auto Inhibit®, which eliminates surging during rapid AC line
switching; pulse transformer triggering, which provides cogless operation at low
speed; and superior noise rejection circuitry, which eliminates false starts and
blown SCRs. Enable (N/C) and Inhibit (N/O) functions provide electronic switching of control output.
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 5 kΩ remote potentiometer and
QD terminals.

OPTIONAL ACCESSORIES
• Auxiliary Heat Sink (Part No. 9861) – Doubles the horsepower rating of
the control.
• Barrier Terminal Board (Part No. 9897) – Converts the quick-connect
terminals of the KBMM™ to a barrier terminal block. Contains PC board
mounted line and armature fuse holders. Plugs onto the quick-connect
terminals of the KBMM.
•
SI-6 Signal Isolator (Part No. 9444) – Provides isolation between nonisolated signal sources and the KBMM™. Plugs onto the quick-connect terminals of the KBMM™. Contains barrier terminal block.
•
Run/Brake Module (Part No. 9952) – Used for applications that require
rapid stopping of the motor. Contains barrier terminal block.
•
Barrier Terminal Accessory Kit (Part No. 9883) – When used with the
Auxiliary Heat Sink, it converts the quick-connect terminals of the
KBMM™ to a barrier terminal block and provides built-in fusing.
•
Dial Plate and Knob Kit (Part No. 9832) – Provides indication of the
Main Speed Potentiometer position (incremented form 0 – 100%).
•
Finger-Safe Cover (Part No. 9564)6– Converts the control from open
chassis to the IP-20 standard.
