Leo is a digital microprocessor-based current regulator for electromagnetic powder brakes, specifically engineered for precise web tension control in converting, printing, packaging and many other industries.
By leveraging a closed-loop current feedback, Leo ensures stable current output to the brake or clutch, even as brake characteristics change over time. This consistent performance is further enhanced by the Antiresidual function, which eliminates residual magnetism and maintains accurate torque at very low levels, guaranteeing constant tension on the material.
Designed to save space and simplify operations, Leo current regulator can be easily mounted on a DIN rail and includes an intuitive interface with three buttons for quick calibration and effortless management.
While it excels in closed-loop configurations, working together with web tension controllers like T-One, T-Two, or a PLC, Leo can also function independently as a tension regulator in open-loop configurations. By using sonar (servo-diameter) or potentiometers, it delivers precise web tension control tailored to your specific production requirements.
In closed-loop configurations equipped with dancer rollers and potentiometers, Leo offers stable and responsive proportional-derivative control, ensuring optimal web tension regulation.
The outcome is a more efficient line, minimized material waste, consistent product quality, and increased productivity, fulfilling the demands of today’s most advanced converting and printing operations.
