KBRG DC Drive SCR Chassis Regen Reversing
KBRG-212D (8819), SCR Regen Reversing Drive, 115/230 Vac Input, 0-130/180 Vac Output, thru 1 1/2 HP, Open Chassis The KBRG-212D is a 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. This allows the control to maintain constant speed with overhauling loads and provides rapid instant reversing and controlled braking. Because of its excellent controllability and response time, the KBRG-212D can replace servos in many applications. The control is factory set for armature feedback, which provides up to 1% load regulation over a motor base speed of 50:1. Tachometer feedback is also provided for superior load regulation if required. A simple jumper setting converts the KBRG-212D to a torque control. In this mode, motor torque rather than motor speed is controlled. An important feature of the drive is the factory-calibrated, built-in, selectable, motor current jumper. It eliminates the need to recalibrate IR Comp and Current Limit for most applications. The control contains an Enable function which can be used to start and stop the motor electronically via a contact closure. Through a jumper selection, the motor can be set to rapidly regenerate to a “stop” or to “coast to stop.” KB’s exclusive Auto Inhibit® circuit provides safe, smooth starting during rapid cycling of the AC line. The Overspeed Protect Circuit prevents failure of the power bridge in extreme overhauling conditions. Reliability of the KBRG-212D is further enhanced with the use of a high speed current limit circuit along with armature fusing 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 provides enhanced heat transfer which provides a higher control rating while maintaining cooler running SCR’s. Several accessories are available for the KBRG-212D, which enhance its adaptability to many applications. They include: Bipolar signal isolator, 4-quadrant accel/decel board, PID compensator and multi speed module. A 5K remote potentiometer and full operating instructions are supplied.
