Dissenyat per a sistemes de doble bateria, el kit Mini Add-A-Battery Blue Sea 7649-BSS simplifica la gestió de la càrrega per a alternadors fins a 65A. Incorpora un relé de càrrega automàtic (ACR) m-Series 7601 i un interruptor de bateria Dual Circuit Plus™ m-Series 6011. Aquest sistema permet una combinació automàtica de les bateries en càrrega i un aïllament durant la descàrrega, protegint així la bateria d’arrencada.

Gestió automatitzada de l’alimentació

El relé de càrrega automàtic (ACR) m-Series 7601 ofereix una gestió intel·ligent de dos bancs de bateries. Combina automàticament les bateries quan una d’elles rep càrrega i les aïlla en cas de descàrrega o en arrencar el motor. Aquesta funció protegeix els equips electrònics sensibles de les baixades de tensió mitjançant l’opció d’aïllament d’arrencada (SI). El relé té una capacitat contínua de 65A i una capacitat intermitent de 115A (5 min), compatible amb sistemes de 12V o 24V DC. Les tensions de tancament són de 13,6V (30 s) o 13,0V (2 min) per a 12V, i 27,2V (30 s) o 26,0V (2 min) per a 24V. Els llindars d’obertura són de 12,35V (10 s) o 12,75V (30 s) per a 12V, i 24,7V (10 s) o 25,5V (30 s) per a 24V. Incorpora també una protecció contra sobretensions (16,0V DC) i contra baixes tensions (9,5V DC per a 12V, 19,0V DC per a 24V).

Seguretat i flexibilitat del sistema

L’interruptor de bateria Dual Circuit Plus™ m-Series 6011 permet commutació simultània de dos bancs de bateries amb un únic commutador ON/OFF, mantenint l’aïllament entre bancs. Ofereix una funció "COMBINE BATTERIES" per a arrencada d’emergència en cas de bateria baixa. Aquest commutador està dissenyat per a un corrent continu de 300A per circuit, 450A en intermitent (5 min) i un corrent d’arrencada de 675A (30 s) per circuit, amb una tensió màxima de 32V DC. Les bornes de cargol de coure estanyat asseguren una conductivitat màxima i resistència a la corrosió, acceptant terminals M10 (3/8"). Tot el kit té classificació IP66/IP67, garantint protecció contra dolls d’aigua forts i immersió temporal fins a 1 metre durant 30 minuts, i està protegit contra la ignició segons les normes ISO 8846 i SAE J1171, cosa que el fa segur per a instal·lacions en embarcacions amb motor de gasolina.

Posicionament i aplicacions

Aquest kit Mini Add-A-Battery Blue Sea 7649-BSS està optimitzat per a embarcacions petites, fora borda, vehicles recreatius i instal·lacions solars fora de xarxa que requereixen gestió d’alternadors fins a 65A. Per a sistemes amb alternadors de major potència, per exemple fins a 120A, Blue Sea ofereix el kit Add-A-Battery 7650, que utilitza un relé SI-ACR 7610 i un interruptor de bateria E-Series 5511E, amb una capacitat superior adaptada a necessitats energètiques més grans. El 7649-BSS és ideal per a una configuració senzilla i eficaç de dues bateries, amb opcions de muntatge versàtils (superfície, panell frontal o posterior) i un botó desmuntable per a seguretat.

« Simplified and secure management of dual batteries up to 65A »

The Blue Sea Mini Add-A-Battery 7649-BSS kit is an integrated solution for lightweight vessels and auxiliary systems requiring efficient management of two battery banks with a maximum 65A alternator. Its advantage lies in simplifying wiring and operation compared to installing a separate battery coupler and charge distributor. The integrated Dual Circuit Plus™ battery switch and automatic charge relay (ACR) enable quick commissioning and intuitive use.

For owners of small sailboats, rigid inflatables, or outboard-powered boats, this kit provides peace of mind by ensuring the starting battery remains available even after prolonged use of onboard equipment on the service battery. The "Start Isolation" function of the relay is particularly relevant for protecting sensitive electronic equipment from voltage spikes and dips during engine start-up. While the system is designed for alternators up to 65A, it is essential to verify your engine alternator's power output to ensure compatibility. For installations with higher-output alternators (e.g., 100A or 120A), it would be more appropriate to consider the Blue Sea Add-A-Battery 7650 version, which features components sized for higher currents.

Installation is simplified by the compact design and multiple mounting options, but it is critical to adhere to the recommended cable cross-sections (minimum 6 AWG for the ACR, 4/0 AWG for the switch) and incorporate appropriate circuit protections (fuses) to ensure safety and compliance with ABYC standards. The tinned copper terminals and IP66/IP67 protection ratings give this kit excellent durability in marine environments.
