KB Electronics - KBRG-240D
REGENERATIVE DRIVE FULL WAVE 4 QUADRANT Variable Speed SCR and Torque Control of PM and Shunt Motors ONE MODEL COVERS: 1/10 - 3/4 Hp (90 VDC) @ 115 VAC - 50/60 Hz - 1/5 - 11/2 Hp (180 VDC) @ 230 VAC - 50/60 Hz 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.
