TYPICAL APPLICATIONS
• Conveyors • Packaging Machines
• Exercise Equipment • Pumps • Feeders
• Screening and Printing Equipment
STANDARD FEATURES
• Plug-in Horsepower Resistor® 5 – Eliminates the need to calibrate control for
IR Comp and Current Limit when used on various horsepower motors.
• Auto Inhibit® – Allows the control to be rapidly switched “on” and “off” using
the AC line.
• Inhibit and Enable – Allows the control to be turned “on” and “off” using
electronic switching.
• Trimpots: MIN & MAX Speed, IR Comp, Current Limit, ACCEL & DECEL
• Model KBMM-225D can operate on 115 or 230 VAC input with 90 or 180
VDC motors. – Jumper selectable.
• Model KBMM-225 operates on 230 VAC input with 90 or 180 VDC motors.
• Armature or Tach-Generator Feedback
• MOV Transient Protection • SMT Construction
• Power On and Current Limit LED Indicators
• Built-in Armature and AC Line Fusing 5
• Main Speed Potentiometer (5 kΩ)
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.
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 11⁄2 HP at
115V and 3 HP at 230V by the use of KB’s auxiliary heat sink. Models KBMM225 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.
