KBCC-225 KB Electronics 16 Amp SCR 230VAC 90/180VDC Anti-Plug Reversing Chassis Drive 9938

KBCC-225 Series of chassis SCR full-wave variable speed DC motor control, now with SMT construction. 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 KBCC™ is further enhanced with the use of high-surge, 25A SCRs and AC line and armature fusing. The KBCC™ 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.

KBCC-225 Series includes all the features of the KBMM™ including the Auxiliary Heatsink and Barrier Terminal Block with AC line and armature fuses. The controls are ruggedly constructed and contain a remote 5K speed pot.

FEATURES:

• Plug-in Horsepower Resistor®5 – Eliminates the need to calibrate control for IR Comp and Current Limit when used on various horsepower motors.
• Tachometer or Armature Feedback
