Description

BI-1203-3A Battery Isolator - 120A - 1 Alternator, 3 Battery

The Arco Marine BI-1203-3A is an inboard/outboard battery isolator that can handle 1 alternator, 3 batteries, and 120A max. Rated for use with 10 to 350-amp alternators on 12, 24, or 32-volt negative ground systems.

*Includes exciter terminal

Features:

1 alternator, 3 batteries, 120A 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.

This product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns.
