Batteria-kiegészítő készlet – 120 A

The BLUE SEA Add-A-Battery 120A kit is an integrated solution designed to simplify the management and automation of charging two separate battery banks, typically a starter battery bank and a house battery bank, from a single charging source. It ensures reliable electrical management without manual intervention and helps prevent starter battery failures.

The Add-A-Battery 120A kit includes two main components:

A Dual Circuit Plus™ e-Series battery switch. A 120-amp automatic charging relay (SI-ACR).

The automatic charge relay SI-ACR included in this kit has a continuous current capacity of 120 amperes. It can also handle an intermittent current of 210 amperes for 5 minutes.

The Dual Circuit Plus™ e-Series battery switch has a continuous current rating of 350 amperes per circuit. It can handle an intermittent current of 525 amperes (5 minutes) and a starting current of 700 amperes (30 seconds) per circuit.

Yes, the Add-A-Battery 120A kit is designed to work with 12V or 24V DC electrical systems.

The "Ignition Protected" marking means that the components of the kit, the SI-ACC automatic charging relay and the Dual Circuit Plus™ e-Series battery switch, are designed to be safe for installation on gasoline-powered motorboats, thereby reducing the risk of fire or explosion from sparks.

The automatic charge relay (ACR) automatically combines batteries during charging and isolates them when discharging or during engine starts. It efficiently shares the load between the two batteries without requiring regulator adjustment or rewiring.

The "Start Isolation" function (startup isolation) provides temporary isolation of service loads from the engine circuit during engine startup. This protects sensitive electronic devices from voltage drops that can occur during startup.

The Dual Circuit Plus™ e-Series battery switch is rated IP66, ensuring protection against powerful water jets.

The SI-ACR automatic charge relay is rated IP67, meaning it is protected against temporary immersion up to 1 meter for 30 minutes.

The battery switch must be installed in an easily accessible location close to the batteries for optimal efficiency.

To minimize corrosion of wires and terminals, the automatic charging relay SI-ACR must be installed in a dry and protected location. It is recommended to avoid mounting it directly above battery banks.

To ensure the Dual Circuit Plus™ battery switch operates within its rated capacity, it is recommended to use a 4/0 AWG (120mm²) cable per terminal.

The studs on the battery switch of the Dual Circuit Plus™ e-Series and the automatic charging relay SI-ACR must be tightened to a torque of 140 in-lbs (15.82 N·m).

A wire must be connected from the quick-connect terminal marked SI (start isolation) to the terminal or wire running from the ignition switch to the starter solenoid. This connection must be made via an inline fuse of one to ten amps and must be positive only during engine start.

Yes, it is possible to connect a remote LED indicator. The red wire of the LED must be connected to a positive source via a 1–2 amp inline fuse, and the yellow wire of the LED must be connected to the quick-connect terminal marked LED on the ACR.

The Blue Sea Add-A-Battery 120A kit is designed to support high-efficiency alternators up to 120 amperes.

Yes, the components in the kit are "ignition-protected", making them safe for installation on boats equipped with gasoline engines.
