ARCO Marine BI-2703 Battery Isolator for 10-350A Alternators on 12, 24, or 32V Systems

BI-2703 Battery Isolator for 10-350A Alternators on 12, 24 or 32V Negative Ground Systems

The Arco Marine BI-2703 is an inboard/outboard battery isolator that can handle 2 alternators, 3 batteries, and 70A max. Rated for use with 10 to 350-amp alternators on 12, 24, or 32-volt negative ground systems.

Features:

• 2 alternators, 3 batteries, 70A max


• Inboard and outboard battery isolators are solid-state devices that allow electrical current to flow in one direction ONLY, thus permitting the alternator to be connected directly to two batteries without fear of one higher-charged battery discharging into the lower-charged battery.


• Both batteries are always being charged automatically, in proportion, to their needs whenever the engine is running.


• When battery isolators are used in conjunction with selector switches, it is not necessary to change the switch position to provide for charging of both batteries.


• Isolators provide proportioning of the output or charging current on the alternator to the batteries as required, regardless of switch position.

NOTE: Battery Isolators cannot be used on 12 volt charging systems with 24 volt trolling motors or newer outboard engines with rectifier-regulator charging systems.

The ARCO Marine BI-2703 Battery Isolator is a robust solution designed specifically for inboard and outboard applications. Capable of handling 2 alternators and connecting up to 3 batteries, this isolator is rated for a maximum of 70A. It is ideal for use with 10 to 350-amp alternators across 12, 24, or 32-volt negative ground systems, ensuring efficient charging and seamless operation.

Features:
* Alternator Compatibility: Supports 2 alternators and 3 batteries with a maximum of 70A.
* Solid-State Design: Allows electrical current to flow in one direction only, preventing higher-charged batteries from discharging into lower-charged ones.
* Automatic Charging: Both batteries receive proportional charging based on their needs whenever the engine is running.
* Selector Switch Flexibility: Works in conjunction with selector switches, eliminating the need for manual switch adjustments for charging.
* Current Proportioning: Ensures output or charging current from the alternator is distributed to batteries as required, irrespective of switch position.
