Dolphin Automatic Charge Selector (ACS) are the ideal charging-relays for any outboard engine boats. Automatically manage and optimize the charging of multiple power sources onboard your vessel. ACS automatically detects and selects the most appropriate charging source for the vessel's battery bank, ensuring that the boat's batteries are always charged optimally, preventing overcharging or deep discharge that could damage the batteries or leave the vessel without sufficient power.

Dolphin cutting-edge “Current Limit Function” is built on MOSFET technology and includes a one-way operating “blocking diode function” preventing battery voltage drop when starting your engine or bow thruster.

Result: no more sensitive electronics damaged onboard (GPS, etc.)
