4 quadrant regenerative DC drive
IP65 (NEMA-4X), 0.1 - 2 HP | KBRC Series KB Electronics, Inc.

The KBRC-240D is a Full-Wave Regenerative Drive in a NEMA-4X/ IP-65 washdown and watertight enclosure. It is designed to operate 90 and 180 Volt Permanent Magnet and Shunt Wound DC motors in a bidirectional mode. It provides 4-quadrant operation, which allows 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 performance, the control can replace servo drives in many applications. The KBRC-240D has a Regeneration Overspeed Protection Circuit, which prevents failure of the power bridge in extreme overhauling condi- tions. Motor overload protection (I x t) will shut down control if the motor is overloaded for a predetermined amount of time. The exclusive Auto-Inhibit ®
circuit allows safe, smooth starting during rapid cycling of the AC line. Due to its user-friendly design, the KBRC-240D is easy to install and operate. Tailoring to specific applications is accomplished via selectable jumpers and trimpot adjustments. However, for most applications, no adjustments are necessary.
The KBRC-240D can be operated from a two or three wire start/stop circuit or can be started from the AC line. Aset of dedicated normally open or normally closed relay contacts are provided, which are activated via the start/stop circuit. They can be used to turn on or off equipment or to signal a warning if the control is put into Stop Mode or times out in TCL. Main features of the KBRC-240D include Speed or Torque control modes.
