K-Series Drives
Fully isolated DC motor control with compact design.
Improving or upgrading your single direction DC motor control system is easier with this series of fully-isolated controllers. The ultra compact DIN rail mounting package lets you quickly integrate the K340i, K680i, and K1220i series with your existing motor control equipment.
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 K340i, K680i, and K1220i series controllers have easy to access drive adjustments, plug-on screw terminals, and a small footprint from just 2.4″ x 4.2″.
