5212 – Current Regulated Power Supply

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] => In tension control applications that have multiple webs or multiple strands, it is very desirable to match the tension of each web or strand. This is most commonly attained by using a closed loop servo control system which controls current to a braking device through the use of dancer arms, follower arms and in-line tension transducers. The problem with such systems is that each web or strand must be individually controlled, increasing the cost and complicating the system with multiple sensors and power supplies.

Magtrol has developed a system to assure that every brake of a given model designation will be matched, at a predetermined torque and current point, to other brakes of the same model designation regardless of material and manufacturing tolerances. Each brake will be matched at the selected match point to within a tolerance of ±1%. The maximum deviation in torque from brake to brake at any point along their torque/current curve (from 0 torque up to the selected matched torque point) will be less than ±4% of the selected matched torque value. With this level of matching, a system with multiple tension rollers would provide tension consistency within ±1% if set at the matched point with all brakes receiving the same current. The matched point can be any value between 50% and 100% of rated torque, which allows the brakes to be optimized for specific applications. Unless otherwise specified, all brakes are matched at 100 rpm.

Typical vs. Matched Brakes

All single Magtrol Hysteresis Brakes can be matched. When ordering, replace the HB in the Hysteresis Brake model number with MHB. For Large Bore Brakes, LB is replaced with MLB.

While best suited to applications where fixed torque is to be applied, adjustable units can be made specifically tailored to the application. Typically provided as brake units, with the addition of an input shaft, the same unit can be used as a clutch. In a clutch application, the pole/case member becomes the drive element, and the rotor/shaft assembly becomes the driven element of the clutch with torque being transmitted through the magnetic air-gap. Magtrol Hysteresis Permanent Magnet devices provide all the superior operating characteristics of smooth operation, precise repeatability and long life inherent in our standard Hysteresis Brakes and Clutches.

The analog input of the Current-Regulated Supply Module is designed for 0 -10 VDC signals. At the maximum set value of 10 VDC, the output current is adjustable from 0 to 100 %.
