5212 – Current Regulated Power Supply
Description du produit
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.

[post_content] => Le module d'alimentation à courant régulé de la série BPM permet d'alimenter et de contrôler la puissance (jusqu'à 3 A) des freins et embrayages à hystérésis de Magtrol. Ce composant compact est un élément facile à mettre en place (encliquetable sur un rail DIN) et une solution recommandée pour facilement contrôler une large gamme de freins et d'embrayages.
L'entrée analogique du module d'alimentation à courant régulé est conçu pour des signaux de 0 à 10 DC. A la valeur de consigne maximale de 10 VDC, le courant de sortie est réglable de 0 à 100 %. A l'aide d'un potentiomètres, le point zéro peut être décalé de 0 à 20 %.

[post_content] => Lorsque la mesure et le contrôle du couple doivent être effectués à la puissance la plus élevée possible, l’utilisation de freins à Hystérésis Magtrol de la série AHB est idéale. Les ouvertures passant par les freins permettent un refroidissement par air comprimé, assurant une excellente dissipation thermique.
Cette conception permet une puissance nominale continue jusqu'à 3000 watts (5300 watts par intermittence). L'utilisation de roulements pré-chargés dans les freins à hystérésis AHB permet un fonctionnement à des vitesses allant jusqu'à 25000 min-1 pour des durées prolongées.
Les freins AHB sont assemblés avec des blocs de jonctions, pour un montage et un câblage aisé.
