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
