Product Summary: Operates off 115/230 Volt AC line, 50/60 Hz. Filtered DC output for cooler motor operation, longer brush life, lower audible noise, and wider speed range.

The KBMG-21D is an ultracompact, full-wave regenerative drive capable of operating DC PM or Shunt motors in a bidirectional mode. Its 4-quadrant operation provides forward and reverse torque in both speed directions. Through a jumper selection, the motor can be controlled to rapidly regenerate to stop or to coast to stop. KBs exclusive Auto Inhibit circuit provides safe, smooth starting even during rapid cycling of the AC line. The Overspeed Protect Circuit prevents failure of the power bridge in extreme overhauling conditions. Reliability of the KBMG is further enhanced with the use of a high speed current limit circuit and MOV transient protection. LED's, which can be used for diagnostics, are provided for power on and motor overload. A rugged extruded aluminum heatsink ensures enhanced heat transfer, which provides a higher control rating while maintaining cooler running SCRs. Power connections to the KBMG are made via quick connect terminals and signal input connections are made via a removable barrier terminal block.

**Plug-In Horsepower Resistor® and Armature fuse supplied separately.

Dimensions: 4.50" x 3.70" x 1.90"

Options include Auxiliary heat sink, Barrier Terminal Board, RFI/EMI filters and Signal Isolation.

UL, CSA, CE, C-tick. (CCC pending) Patented.
