Detailed description

Dissenyat per a la gestió optimitzada dels sistemes elèctrics marins de 12V, el BLUE SEA ATD Automatic Timer Disconnect (referència 7615) és un dispositiu versàtil capaç d’exercir quatre funcions diferents: desconnectar automàticament amb retard, desconnectar per baixa tensió, relé de càrrega automàtic (ACR) i simple solenoide. Aquesta flexibilitat permet consolidar diverses funcions de gestió de bateries en un sol component, simplificant així les instal·lacions complexes.

Gestió de l’alimentació i protecció de bateries

El BLUE SEA ATD 7615-BSS ofereix opcions de desconnectar configurables per protegir les bateries contra la descàrrega excessiva. En mode de desconnectar automàtic amb retard, talla l’alimentació dels aparells després d’un període predefinit que va de 15 minuts a 4 hores, un cop retirat el senyal de 12V. Per a una protecció addicional, el mode de desconnectar per baixa tensió supervisa la tensió de la bateria i aïlla automàticament les càrregues quan aquesta arriba a un llindar ajustable (11,0V, 11,5V o 12,0V), amb un retard de 10 segons per evitar disparaments intempestius. Aquesta funció es pot combinar amb la desconnectar automàtic amb retard per una gestió proactiva.

Funcionalitats de relé de càrrega i solenoide

Com a relé de càrrega automàtic (ACR), el BLUE SEA ATD 7615 combina automàticament dos conjunts de bateries per a la càrrega des d’una única font, i després els aïlla durant la descàrrega. El seu disseny amb detecció unilateral supervisa la tensió de la bateria d’arrencada, fent-lo adequat per a bateries auxiliars AGM o de major capacitat. El dispositiu es connecta quan la tensió arriba als 13,0V durant 3 segons i es desconnecta si baixa per sota dels 12,75V durant 10 segons. Finalment, el ATD 7615 pot funcionar com un solenoide simple, activant o desactivant el relé instantàniament mitjançant un senyal de 12V, sense retard.

Robustesa i conformitat amb normes marines

L’ATD 7615-BSS està dissenyat per a entorns marins exigents, amb protecció contra la immersió fins a 1 metre durant 30 minuts (IP67). Està marcat amb el segell CE i compleix els requisits de protecció contra la inflamació externa ISO 8846 i SAE J1171, assegurant una seguretat addicional. Amb una capacitat de corrent continu de 120A i intermitent de 210A (5 min), és compatible amb cables fins a 1/0 AWG (50mm²) mitjançant cargols M10. La configuració es realitza mitjançant commutadors DIP, permetent una adaptació precisa a les necessitats del sistema. Una protecció contra sobretensions desconnecta el dispositiu si la tensió supera els 16,0V durant 5 segons.

« Versatility and protection: the BLUE SEA ATD 7615 for simplified electrical management »

The BLUE SEA ATD 7615 stands out as a key component for streamlining electrical installations on mid-sized sailboats and powerboats. Its unique ability to integrate multiple energy management functions into a single unit sets it apart from traditional modular solutions. Instead of installing separate automatic charge relays, timed circuit breakers, and low-voltage disconnect devices, the ATD 7615 centralizes these roles, reducing wiring complexity and clutter. This consolidation is particularly beneficial in confined technical spaces.

In terms of practical use, this device is ideal for owners looking to automate protection of their service batteries against deep discharges, or for those who want automatic disconnection of non-essential loads after engine shutdown or a period of inactivity. For example, it can be configured to automatically turn off deck lighting or navigation electronics after a set time, or to isolate the service bank if its voltage drops dangerously, thereby preserving the starter battery. Its ACR function is relevant for dual-battery systems where the charging source is single and unilateral detection (on the starter battery) is sufficient.

Installation requires an understanding of marine electrical schematics, particularly for cable sizing (up to 1/0 AWG) and the integration of appropriate fuses. It is critical to note that the BLUE SEA ATD is not designed to handle engine start currents. If used as an ACR, it must not be employed to combine batteries in emergency starting scenarios; a dedicated battery switching system with coupling function is then required. DIP switch configuration is straightforward and intuitive but requires physical access to the unit. The mounting location must be dry and protected to prevent connection corrosion, though its IP67 rating provides significant resistance to moisture.
