  • MAGPOWR LC-500G Low Tension Load Cells

    Lightweight single strand applications including wire, fiber optics and filament textiles face the requirements of tension measurement. For various reasons, lighter, thinner, finer materials are now demanded, and manufacturers require tension controls that can help facilitate those demands.

    MAGPOWR’s Low Tension Load Cells (LC-500G & LC-500GS1) have full wheatstone bridge strain gage configurations, and the meet the same industry leading specifications as all other MAGPOWR load cells. The LC-500G, designed to mount easily into almost any single strand installation, also employs 360 degrees of overload protection preventing the need for recalibration in the event of overload situations. For applications requiring special pulleys, the LC-500GS1 is available with provisions for a customer-supplied pulley.

  • MAGPOWR PA-90 and PA-2 Power Amplifiers

    MAGPOWR’s PA-90 and PA-2 Power Amplifiers are designed to provide the extra current required for controlling magnetic particle brakes and clutches in any tension control application. For use with DIGITRAC II, EZ-Trac, or VERSATEC, the PA-90 and PA-2 can be mounted inside the control’s enclosure, and receives its control signals directly from the tension control.

    The PA-90 is used to control 90 VDC brakes and clutches only, while the PA-2 can be used to control either 24 or 90 VDC units. MAGPOWR’s power amplifiers also include reverse current circuitry as a standard feature, thus allowing greater controllability in the lowest torque range of the clutch or brake being operated.

  • MAGPOWR Perma-Tork Permanent Magnet Clutches and Brakes

    Smooth, precise control is the objective of all clutches and brakes, but few achieve one—never mind both—of these goals. MAGPOWR’s innovative Perma-Tork® permanent magnet clutches are capable of producing highly accurate, dependable torque, without the need of an external power source. The clutches (available in hysteresis or magnetic particle) use high energy, multi-pole magnets to establish lines of magnetic force that retard the motion of the center rotating disc, delivering smooth, precise control.

    Designed for long-lasting, reliable performance, Perma-Tork clutches are commonly used in light torque control applications, including tensioning, torque limiting, magnetic coupling and testing.

  • MAGPOWR TC-5 Power Supply for Clutches and Brakes

    Dependable current-regulated power supplies are imperative for the proper operation of all magnetic particle clutches and brakes, and MAGPOWR’s are no different. The MAGPOWR TC-5 is a solid state current regulated 90 VDC power supply. It has four current ranges of 1/8, 1/4, 1/2 and 1 amp, selected by a simple jumper on the circuit board. This unit also includes reverse current circuitry as a standard feature, thus allowing greater controllability in the lowest torque range of the clutch or brake being operated. The TC-5 is easy to work with, as the front panel meter indicates the current output and automatically reads full scale for each current range selected. The operator controls the output by rotating the front panel potentiometer.

  • MAGPOWR PS-24 and PS-90 Power Supply for Clutches and Brakes

    Complete control is the goal of any operation utilizing brakes and clutches. MAGPOWR’s PS-24 & PS-90 Power Supplies provide a small amount of reverse current circuitry as a standard feature to minimize the drag torque of a clutch/brake, allowing greater controllability in the lowest torque range.

    These power supply units control any size MAGPOWR clutch or brake with optimum resolution. MAGPOWR’s current-regulated power supplies are used for the control of magnetic particle clutches and brakes in unwind, rewind, or intermediate tension control applications. With selectable current ranges, these compact enclosures can be mounted inside the machine cabinet, allowing your operator to adjust torque through a remotely mounted potentiometer or with a 0 to 10 vdc control signal from MAGPOWR Open Loop and Closed Loop controllers, or any control device like a computer or PLC.

  • MAGPOWR TSU Under Pillow Block Load Cells

    Ruggedly constructed to stand up to mill duty and with built-in mechanical overload stops in both force directions, MAGPOWR’s TSU Under Pillow Block Load Cells can be bolted under your present roll support bearings and they will accurately measure the tension forces on the machine sensing the roll created by the web. It can display and control the web tension through MAGPOWR tension readouts and controls.

    The TSU is best used with two load cells, one under each pillow block bearing that supports the sensing roll, which then will accurately measure the total force on the entire roll created by tension in the web, and the readout will be precisely displayed no matter what the position of the web.
