The CMC420 is a low voltage controller of Cognitio Elektronika for AC and DC motors. Reliable, robust, and therefore highly cost-effective. It is primarily intended for motion control (actuators, solenoids), but it can also be used for auxiliary systems such as pumps, compressors, auxiliary lighting etc. Its benefits come to light in applications where space saving and high system integration are important . This controller has the ability to drive up to 4 motors, from which up to two AC or DC motors up to 600 W and up to two DC motors up to 150 W. The basic model comes with an aluminum colling surface for custom cooling in the system to which is mounted.

The controllers motor control algorithm and the enclosure can be tailored to the client’s needs for a very wide range of uses.
