VLT® Lift Drive LD 302

  • Fonctionnement fiable et excellent confort

    Le VLT® Lift Drive est conçu pour assurer un fonctionnement fiable et un excellent confort de transport pendant au moins 2,1 millions de cycles à une température ambiante inférieure à 45 °C. Idéal lors de nouveaux projets ou de rénovations, il fonctionne sans contacteur de moteur et peut être mis en service rapidement et facilement en moins de 10 minutes.

    Conçu pour tous les moteurs, y compris ceux asynchrones, à induction, à aimant permanent, à rotor en cuivre et à aimant permanent direct sur le secteur, le VLT® Lift Drive convient à la fois pour les élévateurs de traction et hydrauliques dans des systèmes à boucle ouverte ou fermée.

    Le concept compact et intelligent de refroidissement lui permet de s'adapter facilement, même aux espaces les plus réduits. De plus, une gamme de fonctions intégrées élimine la nécessité d'installer des composants supplémentaires. Les filtres RFI atténuent les interférences électromagnétiques, les selfs CC intégrés suppriment les harmoniques tout en garantissant que les variateurs soient conformes aux normes CEM ; des transformateurs élévateurs et abaisseurs ne sont pas nécessaires.

    380-400 V...4-55 kW

    Caractéristiques et avantages

    • Le confort de transport est accru grâce à une gamme de fonctions réduisant le niveau de bruit
    • Des économies d'énergie peuvent être réalisées pendant le fonctionnement des ventilateurs uniquement lorsque c'est absolument nécessaire
    • La mise en service du variateur est rapide et facile parce qu'il s'adapte à tous les systèmes de retour courants et qu'il n'y a que 10 paramètres à régler
    • Le variateur fonctionne de manière fiable dans des conditions difficiles grâce aux cartes de circuit tropicalisées
    • Les composants restent bien en place dans les environnements à hauts niveaux de vibrations grâce à la « version renforcée »

    Applications
