Dolphin ACS 12V 80A Auto Charger Selector

Dolphin ACS Auto Charger Selector (12V, 80A) is a smart, 100% waterproof (IP67) and compact voltage-sensing relay that automatically manages the charge function between start and service battery banks. It is designed as the ideal charging relay for outboard engine boats.

The unique SuperSafe feature uses MOSFET technology with a one-way blocking diode function, preventing service battery voltage drop when starting the engine or bow thruster — protecting sensitive electronics like GPS from damage. Intrinsically safe against ignition of flammable vapors per ISO 8846, this ACS is safe for gasoline outboard boats, reducing amperage operating current by up to 70% compared to other voltage-sensing relays, and is particularly recommended for use with lithium batteries.
