KBRG-255 Regenerative Drive

Products Description
The KBRG-255 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-255 can replace servos in many applications. The control is factory set for armature feedback, which provides ip to 1% load regulation over a motor base speed of 50:1. However, tachometer feedback is also available if superior regulation is required.
