5251-2 – Current Regulated Power Supply
Description du produit
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 %.

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] => 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.
