ARCO Marine BI-1202 Battery Isolator for 10-350A Alternators on 12, 24 or 32V Systems

BI-1202 Battery Isolator for 10-350A Alternators on 12, 24 or 32V Negative Ground Systems

The Arco Marine BI-1202 is an inboard/outboard battery isolator that can handle 1 alternator, 2 batteries, and 120A max—rated for use with 10 to 350-amp alternators on 12, 24, or 32-volt negative ground systems.

Features:

• 1 alternator, 2 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.

The ARCO Marine BI-1202 Battery Isolator is designed for inboard and outboard use, offering superior performance for 10 to 350-amp alternators in 12, 24, or 32-volt negative ground systems. This solid-state device allows seamless electrical flow to two batteries, ensuring they are charged proportionally while preventing the discharge of a higher-charged battery into a lower-charged one. With a maximum capacity of 120A, the BI-1202 is a reliable choice for ensuring both batteries are always charged when the engine is running. Use it with selector switches for hassle-free operation, as it automatically manages charging without needing to change switch positions.

Features:
* Max Capacity: 120A for 1 alternator and 2 batteries
* Solid-State Design: Ensures current flows in one direction only, safeguarding battery health
* Automatic Charging: Both batteries are charged according to their needs while the engine operates
* Selector Switch Compatibility: No need to change switch position for charging both batteries
* Proportional Charging: Output current from the alternator is distributed according to battery requirements
