The M-4272 Digital Motor Bus Transfer system provides automatic and manual

 transfers of motor bus systems in power plants and industrial processing plants,

to ensure process continuity. For any critical application in which losing power

is unacceptable, the M-4272 seamlessly handles transfer to backup power sources.

It automatically selects fast, in-phase, residual voltage, and fixed time motor bus

transfers, based on system conditions.

It is applicable for both one way and bi-directional manual and automatic transfers

and can be expanded to accommodate multiple breaker configurations.

Additional features of the M-4272 include:

• Multiple setpoint profiles for various application requirements.

• Integrated control, supervisory functions, sequence of events, and oscillograph

recording.

• Extensive commissioning tools, including ringdown analysis.

• Optional M-3919A Graphic Display Unit (GDU) and Touch Screen Human Machin

Interface (HMI) for communicating with one or two M-4272 units.

• Optional M-5072 Retrofit Kit for M-4272 Replacement of M-0272/M-0236B Analog

Transfer Logic Controller.

• Fournit des transferts Automatiques et Manuelles des systèmes de l’autobus

dans les centrales électriques et les usines de transformation industrielle

• Assure la continuité des processus

• Sélectionne automatiquement Rapide, En-phase, Tension Résiduelle,

et Temps Fixe transferts du moteur de bus, en fonction des conditions

variables du système

• Applicable pour transferts Manuels et Automatiques, unilateraux et

bi-directionnelles

• Peut être agrandi pour accueillir des configurations multiples disjoncteurs

• Plusieurs profils de consigne pour les besoins de diverses applications

• Contrôle intégré, des fonctions de surveillance, la séquence des

événements et l'enregistrement oscillographe dans un seul appareil

• Nombreux outils de mise en service, y compris anneau analyse

descendante

• Unité d'Affichage Graphique (UDG) M-3919 optionnelle et Écran

Tactile avec Interface Machine-Homme (IMH) pour communiquer

avec une ou deux unités M-4272

• En option Kit d'adaptation M-5072 pour Remplacement de

M-4272 de la commande analogique de transfert logique

M-0272/M-0236B
