KBRG-212D KB Electronics 7.5 Amp 4-Quadrant REGEN Chassis Drive 115/230VAC 8819

KBRG-212D FULL-WAVE 4 QUADRANT REGEN DRIVE 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 Drive is 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.
