        PowerPro24 for precise tension control

        The Latest Innovation in Tension Control

        Magnetic Technologies PowerPro24 (MPP24) is a modern, microprocessor controlled constant current digital power supply and tension controller. MPP24 is specifically designed for use with our line of Electric Hysteresis Brakes.

        We have been involved in the wire, cable, and tension-control industries for over 30 years, transforming it from?leather and rope brakes to permanent magnet brakes for better tension control. However, in the 21st century, the need for even more precise tension control is becoming more prevalent, and maintaining constant tension in payoff applications has become a necessary prerequisite for precision manufacturing in the industry.

        When we began building constant tension controlled payoffs, we found the industry offered no complete tension control solutions. The solutions that were available required?numerous expensive and complicated components and days to setup, calibrate, and tune.

        As we encountered more applications that required precisely controlled constant tension, we used our experience and expertise in the field to develop the first fully integrated tension controller power supply. After years of development, the MPP24 has allowed us to increase tension accuracy, decrease packaging size, and decrease system complexity, all while significantly decreasing total system cost.?

        Operating Modes

        Constant Current

        The user selects a current output. MPP24 will?adjust voltage as the brake heats from normal use to achieve a constant current output and thus constant torque from the brake. Current output can easily be changed on-the-fly.

        0-10VDC Input

        Current is controlled via a 0-10VDC input signal. This input can be from an external source such as a programmable logic controller, a voltage divider follower arm (utilizing the onboard 10VDC power supply), or any other 0-10VDC signal source.

        Ultrasonic Probe

        Sophisticated control algorithms are used to achieve constant tension control. An ultrasonic?probe is used to measure spool diameter. The user enters a desired tension value and?MPP24 constantly adjusts the brake to maintain constant tension.

        Strain Gauge

        Strain gauge mode uses an inline roller load cell to monitor line tension. The user enters a desired tension value and MPP24 uses a PID control algorithm to continuously adjust brake torque to achieve constant tension.

        A Complete Solution

        For use with potentiometer, follower arm, or any other accessory requiring a 10VDC signal

        Integrated 24VDC Source

        For use with accessories such as ultrasonic probe, laser probe, or any other 24VDC device

        Integrated Strain Gauge Amplifier

        Onboard strain gauge amplifier with adjustable gain amplifier allows compatibility with a wide range of inline roller load cells

        Conventional System

        • Used to power a follower arm unit in open-loop control

        • An ultrasonic probe, laser probe, or other diameter sensor in an open-loop system requires a 24VDC voltage source

        • In order to use a inline roller load cell, an amplifier must be used to provide an excitation voltage and amplify the millivolt output signal

        • For closed-loop tension control, a PID tension controller is required, this takes the signal from the strain gauge and outputs a 0-10VDC signal to the constant current power supply

        • The electric hysteresis brake must be powered by a constant current power supply

        • An ultrasonic measurement probe is used to measure spool diameter. The probe?must be powered by an independent 24VDC power supply.?The probe supplies a 0-10VDC signal to the power supply.

        • The electric hysteresis brake will provide a precise drag torque to the spool in order to achieve constant tension payoff
