KBRG-255 (8821), DC Drive Regen Reversing, 5 HP, 230 Vac Input

KBRG-255 (8821), DC Drive Regen Reversing, 5 HP, 230 Vac Input, 0-180 Vdc Output, Chassis 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 up to 1% load regulation over a motor base speed of 50:1. However, tachometer feedback is also available if superior regulation is required. By resetting mode jumper J7 to the “TRQ” position, the KBRG-255 can be changed from a speed control to a torque control. The drive contains a variety of “selectable” jumpers and adjustment trimpots to allow custom tailoring for exact requirements. For example: jumper J6, when placed in the “TCL” position, provides adjustable timed current limit from 1 to 15 seconds. This feature will protect the motor and control by shutting the drive down after the preset time has elapsed. The KBRG-255 can be operated with either a two (2) or three (3) wire start/stop circuit, or can be started from the AC line. A set of dedicated relay contacts are provided which are activated via the start/stop circuit. They can be used to turn on or off corresponding equipment or to sound an alarm if the drive stops. Another important feature is the array of the LED’s, which indicate the mode of operation the drive is in, and also serve as a diagnostic tool. In addition, 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-255 is further enhanced with the use of a high speed current limit circuit. MOV transient protection is also included. A 5K remote potentiometer and full operating instructions are supplied Dimensions: 7.70" x 12.00" x 3.40"
