Produktbeschreibung

Model 5251-2 is an open frame, 0-1A current regulated power supply for use with Magtrol hysteresis brakes and clutches. It has a high input impedance that allows for a variety of sensors and transducers to be used. It features a selectable 0-100 mV/0-5 VDC monitor out that allows connection to a PLC, voltmeter, display or other monitoring device. This allows the user to monitor the current applied directly to the brake or clutch, if desired. With regulated current, torque drift caused by temperature changes within the brake coil is eliminated. Braking control is enabled by using either a 10-turn potentiometer or by an external 0–5 VDC control signal.

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] => Magtrol hat ein System entwickelt, welches garantiert, dass jede Bremse eines bestimmten Typs und Drehmoment/Strom-Arbeitspunkts mit jeder anderen Bremse desselben Typs, ungeachtet der Material- und Herstellungstoleranzen, abgeglichen werden kann.

Der Abgleich jeder Bremse im gewählten Arbeitspunkt erfolgt innerhalb einer Toleranz von ±1%. Die maximale Drehmomentabweichung von Bremse zu Bremse auf der gesamten Drehmoment/Stromkurve (von Drehmoment 0 bis zum ausgewählten, abgeglichenen Arbeitspunkt) übersteigt nicht ±4% des gewählten, abgeglichenen Drehmomentwerts. So abgeglichen und vorausgesetzt, dass alle Bremsen im Abgleichspunkt gleich erregt werden, kann die Zugkraft eines Systems mit einer grossen Anzahl von Zugkraftregulierungen innerhalb eines Toleranzbereichs von ±1% gehalten werden. Der gewählte Arbeitspunkt kann frei zwischen 50 und 100% des Nenndrehmoments gewählt werden. Dadurch können Bremsen für spezifi sche Anwendungen optimiert werden. Ohne andere Spezifikationen sind alle Bremsen auf 100 U/min abgeglichen.

Standard Bremsen gegenüber abgeglichene Bremsen



Abgeglichene Bremsen

Alle Magtrol Hysteresebremsen können abgeglichen werden. Bei der Bestellung muss einfach in der Modelnummer der Bremse HB durch MHB ersetzt werden. Bei Hohlwellenbremsen wird LB durch MLB ersetzt.

                    [post_content] => 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.

Das kompakte Bauteil ist einfach zu montieren (Schnappbefestigung auf DIN-Schiene) und wird zur einfachen Steuerung diverser Bremsen und Kupplungen empfohlen.

Die Analogeingänge des Versorgungsmodul mit geregeltem Strom ausgang sind für 0-10 VDC-Signale vorgesehen. Beim maximalen Sollwert von 10 VDC kann der Ausgangsstrom zwischen 0 bis 100 % eingestellt werden. Das justierbare Potentiometer dient der Nullpunkteinstellung zwischen 0 bis 20 %.

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.
