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

ACS Auto Charger Selector - 12V - 50A

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.

The Dolphin Charger ACS Auto Charger Selector (Part Number: 99206) is a versatile, intelligent relay designed specifically for marine applications, especially outboard engine boats. This 12V, 50A device features a compact and waterproof IP67-rated enclosure, ensuring reliable operation in harsh aquatic environments. Its primary function is to automatically manage charging between your start and service battery banks, eliminating the need for manual switching and reducing the risk of drained batteries. The ACS's smart voltage-sensing technology dynamically detects battery status, providing seamless power distribution to keep your boat’s electrical system running smoothly.
The ACS incorporates advanced safety features, including a unique super-safe current limit function built on MOSFET technology. This feature includes a one-way operating blocking diode that prevents voltage drops on your house or service batteries during engine startup or when using a bow thruster. As a result, sensitive electronics such as GPS units are protected from voltage fluctuations. Additionally, the system is intrinsically safe against ignition of flammable vapors, meeting ISO 8846 standards, making it suitable for gasoline-powered boats. The device's energy efficiency is notable, reducing operating current by up to 70% compared to traditional voltage-sensing relays, which is especially beneficial when using lithium batteries.
Constructed for durability and safety, the Dolphin Charger ACS is IP67 waterproof, ensuring protection against water ingress. Its design includes a multi-color LED indicator and a remote operation switch contact, providing easy status monitoring and control. With no moving parts and a high reliability profile, this relay minimizes maintenance and failure risks, offering a long-lasting solution for boat electrical systems. Whether upgrading an existing setup or installing new, the ACS ensures optimal battery management, safety, and efficiency, making it an essential component for modern marine electrical systems.
