5251-2 – Current Regulated Power Supply
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.

[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.

[post_content] => Wie bei Hysteresebremsen entwickeln Hysteresekupplungen ihr Drehmoment ausschliesslich durch die Magnetkraftübertragung über einen Luftspalt. Dadurch wird eine absolut sanfte Drehmomentübertragung vom Antrieb zum angetriebenen Element garantiert. Ohne Bürsten oder Schleifring gespiesen und als reine Hystereseeinheit konzipiert, welche nicht von Magnetpulver oder Friktionselementen abhängt, werden Hysteresekupplungen weder durch Abnützungserscheinungen noch durch Lecks beeinträchtigt. Magtrol-Hysteresekupplungen und -bremsen eignen sich deshalb vorzüglich für Einsätze in der Lebensmittel- oder Pharmabranche.
