KBMM-125 SCR Chassis Drive 115VAC 90VDC 1-WAY 9449

KBMM-125, 9449 - In Stock
KBMM Is a full-wave DC motor control is the ultimate in reliability and performance. Contains Direct-Fed current limit that helps protect the SCR power bridge against direct shorts and prevents demagnetization of PM motors.

Direct fit replacement Baldor's BC141

KBMM Speed range is 50:1 with load regulation of 1%. Features include: AC Line fuse and Armature Fuse holder, Auto Inhibit®, Voltage Following, MOV transient protection, 5K speed pot and trim-pot adjustments for Min, Max, Accel, Decel, IR and CL. Full-wave variable speed DC motor controls, now with SMT construction. The control is supplied with a 5 kΩ remote potentiometer and QD terminals. The controls contain a unique, super fast, Direct-Fed™ current limit circuit that helps to protect the SCR power bridge against direct shorts. The reliability of the KBMM™ is further enhanced with the use of high-surge, 25A SCRs and AC line and armature fusing. The KBMM™ is fitted 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. In addition, the rating of the control can be extended to 1.5 HP at 115V by the use of KB’s auxiliary heat sink. 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-.
