K-Series Drives
Regenerative DC motor control with compact design. Fully isolated control electronics.
This 4-Quadrant regenerative DC motor controller gives a fast controlled response over the full forward/reverse speed range for motoring and braking.
Improve your energy efficiency by regenerating energy into the mains supply whilst under braking. The energy invested accelerating the load mass is recovered when braking. There is no dissipation of energy in wasteful braking resistors.
The compact DIN rail mounting package uses less panel space so you can save space as well as energy.
Three options are available for controlling DC motors up to 12.2 Amps. You can use this versatile series of fully-isolated controllers for permanent magnet or shunt wound motors.
To make your installation quick and simple, all K340XRi, K680XRi, and K1220XRi series controllers have easy to access drive adjustments, plug-on screw terminals and a small footprint from just 2.4″ x 4.2″.
