Clutch and brake tension controller LEO

digitalweb

Leo is a microprocessor controlled digital current regulator very versatile, compact, reliable and accurate. It can be used both as current regulator in closed-loop systems and as tension controller in closed-loop and open-loop systems. In closed-loop systems it works as web tension controller proportional-derivative, with dancing roller and potentiometer, while in open-loop systems it is combined with sonar (servodiameter) or potentiometer. Thanks to the possibility to cancel any residual magnetism, Leo is able to operate also with low torque applications.
