Pakki til viðbótarrafhlöðna - 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 (service) 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. An automatic charging relay (SI-ACR) rated at 120 amperes.

The automatic charge relay SI-ACR included in this kit has a DC 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 DC current rating of 350 amps per circuit. It can handle intermittent current of 525 amps (5 minutes) and starting current of 700 amps (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 (Ignition Protected) means that the kit components, the SI-ACR automatic charge relay and the Dual Circuit Plus™ e-Series battery switch, are designed to be safe for installation aboard gasoline-powered boats, 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 charge between the two batteries without requiring regulator adjustment or rewiring.

The "Start Isolation" function (start-up isolation) temporarily isolates service loads from the engine circuit during engine start-up. This protects sensitive electronic devices from voltage drops that can occur during start-up.

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

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

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

To minimize corrosion of wires and terminals, the automatic charge 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 meets its rated capacity, use 4/0 AWG (120mm²) cable per terminal.

The studs on the Dual Circuit Plus™ e-Series battery switch and SI-ACR automatic charging relay terminals 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 when the engine is cranking.

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 handle high-efficiency alternators up to 120 amperes.

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