99206 - Dolphin Charger ACS Auto Charger Selector - 12V - 50A

ACS Auto Charger Selector - 12V - 50A

Our Automatic Charge Selectors are smart, 100% waterproof (IP67) and compact voltage-sensing relays that automatically manage the charge function between your start and service battery banks. DOLPHIN ACS are the ideal charging-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 damaged onboard (GPS, etc.).

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

SuperEfficient

No more manual battery selection. No more drained batteries. 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 with Lithium 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.

Specifications:

• System voltage: 12 Volts
• Current rating: 50 Amp Continuous / 120 Amp Peak, 80 Amp Continuous / 190 Amp Peak
• ACS units come with a multi-colour LED control and a remote operation switch contact

The Dolphin Charger ACS Auto Charger Selector (part number 99206) is a voltage-sensing relay designed to automate battery charge management in 12V systems. This device is suitable for environments requiring robust, waterproof electrical components, such as those found in outboard engine boats. It manages the charge function between start and service battery banks, eliminating the need for manual battery selection. A key feature is its Current Limit Function, which utilizes MOSFET technology and a one-way blocking diode to prevent voltage drop in the service battery during engine or bow thruster startup, thereby protecting sensitive onboard electronics. The ACS is intrinsically safe against ignition of flammable vapors (ISO 8846 compliant) and is IP67 certified for waterproofing. It is also recommended for use with Lithium batteries and offers reduced amperage operating current compared to other voltage-sensing relays.
