Product ManualProduct Datasheet

Produktbeschreibung

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] => 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.

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 %.

                    [post_content] => Magtrol’s Permanentmagnet-Hysteresebremsen und –kupplungen eignen sich hervorragend für Einsätze, bei denen die Bremse oder Kupplungsspule nicht mit elektrischem Strom versorgt werden kann. Obwohl sie bestens für Anwendungsfälle geeignet sind, bei denen ein festes Drehmoment einwirken soll, können speziell auf das Anforderungsprofil abgestimmte Verstelleinheiten angefertigt werden. Diese Bauteile werden normalerweise als Bremseinheiten geliefert, können jedoch durch Ergänzung einer Eingangswelle auch als Kupplung verwendet werden. Bei einer Kupplungsanwendung wird das Stator/Gehäuse-Bauteil zum Antriebselement und die Rotor/Wellen-Einheit zum angetriebenen Element der Kupplung, wobei Drehmomente durch ein Magnetfeld im Luftspalt übertragen werden. Magtrol’s Permanentmagnet-Hysteresebremsen zeichnen sich durch hervorragende Betriebseigenschaften aus. Präzise Wiederholgenauigkeit, Sanftlauf und Langlebigkeit sind unseren Standard Hysteresebremsen und Kupplungen eigen.

                    [post_content] => Sollen Drehmomentmessung bzw. Drehmomentsteuerung bei höchstmöglicher Leistung erfolgen, sind die Hysteresebremsen der Serie AHB ideal. Durchgehende Rillen in der Bremse sorgen für Druckluftkühlung und dadurch hervorragende Wärmeableitung. Die Bauweise ermöglicht Dauerleistungen bis 3000 Watt (5300 Watt periodisch). Der Einsatz von vorgespannten Lagern bei den Hysteresebremsen der Serie AHB gestattet sogar Geschwindigkeiten von bis zu 25,000 U/min über einen längeren Zeitraum.

Die Bremsen der Serie AHB sind praktisch auf einer Grundplatte montiert. Die Grundplattenmontage mit einer integrierten, abgrenzbaren Klemmleiste bietet einfache Montage und Verdrahtung.

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.
