Dolphin Charger ACS Auto Charger Selector 12V 80A for Marine Battery Management

ACS Auto Charger Selector - 12V - 80A

OurAutomatic Charge Selectorsare smart, 100% waterproof (IP67) and compact voltage-sensing relays that automatically manage the charge function between your start and servicebattery banks. DOLPHIN ACS are the idealcharging-relays for outboard engine boats.

SuperSafe (Unique feature)

Our cutting-edge Current Limit Function is built on MOSFET technology and includes a one-way operating blocking diode function: this prevents domestic (house/service) battery voltage drop when starting your engine or bow thruster. Result:no more sensitive electronics damagedonboard (GPS, etc.).

ACS is also intrinsicallysafe against ignitionof atmospheric flammable vapours (ISO 8846), which makes it safe for installation on gasoline outboard engine boats.

SuperEfficient

No more manual battery selection. No moredrainedbatteries. Our ACS reduces amperage operating current by up to 70% in comparison with other voltage-sensing relays currently on the market. Our ACS is particularly recommended for use withLithium batteries.

100% WaterProof

ACS products are true Dolphins: they are IP67 certified.

Other assets...

With ACS, forget manual battery selection. Forget moving parts with a high failure rate. Forget battery voltage drop. Forget drained batteries. And, last but not least, DOLPHIN ACS reduces operating amperage by up to 70% in comparison with other voltage-sensing relays currently on the market.
