5212 – Current Regulated Power Supply

Product ManualProduct Datasheet

Product Description

The 5212 is a 0-1A current-regulated 24 VDC power supply and display that is designed for use with Magtrol’s hysteresis brakes and clutches. It features a 10-turn current adjustment potentiometer and 3 selectable current ranges: 200 mA, 500 mA, and 1000 mA. A convenient built in panel meter displays the value of output current.

The 5212 is designed as a closed-loop power supply to provide smooth application of current throughout an entire range up to a maximum set point. By utilizing regulated current, fluctuations in brake torque caused by temperature changes within the brake coil are eliminated. Braking current can be controlled manually from the front panel using the 10-turn potentiometer. Alternatively, if remote operation is required, the 5212 can be controlled by an external source using the 0-5 VDC control input located on the rear panel.

                    [post_content] => Pure Hysteresis Brakes produce torque strictly through a magnetic air gap without the use of magnetic particles or friction components. This method of braking provides far superior operating characteristics (smoother torque, longer life, superior repeatability, high degree of controllability, and less maintenance and down time) which make them the preferred choice for precise tension control during the processing of nearly any material, web or strand.

                    [post_content] => Like the Hysteresis Brake, the Magtrol Hysteresis Clutch develops torque strictly through a magnetic air-gap, ensuring an absolutely smooth transmission of torque from the drive unit to the driven element. Designed to be powered without the use of brushes or slip rings, and being a pure hysteresis device, there is never any fear of contamination due to wear particles or leaky seals. This makes Magtrol Hysteresis Clutches and Brakes ideal for use in food processing and clean room environments.

These magnetic powder brakes provide full torque at zero speed and are convection or air cooled, allowing power ratings up to 900 W (2 100 W with air cooling).
