We over engineer our parts to exceed and outlast O/E standards, often times engineering out any part deficiencies.

Established in 1960, we were pioneers in the O/E replacement parts segment and have a reputation synonymous with premium quality and part reliability. Isolators provide proportioning of the output or charging current on the alternator to the batteries as required, regardless of switch position.ĪRCO Marine is a USA based manufacturer located in Pensacola FL. 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. Both batteries are always being charged automatically, in proportion, to their needs whenever the engine is running.

INBOARD AND OUTBOARD BATTERY ISOLATORS are solid-state devices which 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. NOTE: Battery Isolators cannot be used on 12 volt charging systems 2ith 24 volt trolling motors or newer outboard engines with rectifier-regulator charging systems. All-in-one function with Power supply, DC-UPS, battery charger and status monitoring in ONE. Rated for use with 10 to 350 amp alternators on 12, 24, or 32 volt negative ground systems. Built-in constant current limiting circuit (RSP-75/100/150).
