Dolphin Charger 99206 ACS Auto Charger Selector 12V 50A

The Dolphin Charger ACS (Automatic Charge Selector) is a smart, IP67 waterproof voltage-sensing relay that automatically manages the charging function between your starting and service battery banks. This intelligent device eliminates the need for manual battery selection switches while protecting your sensitive electronics from voltage drops during engine starting.

Key Features:

• 12V system voltage with 50A continuous current rating (120A peak)
• IP67 certified - 100% waterproof and dustproof construction
• MOSFET-based Current Limit Function with blocking diode protection
• Prevents service battery voltage drop when starting engines or bow thrusters
• ISO 8846 certified - intrinsically safe against ignition of flammable vapors
• Reduces operating amperage by up to 70% compared to conventional voltage-sensing relays
• Multi-color LED control indicator with remote operation switch contact
• No moving parts for enhanced reliability
• Particularly recommended for lithium battery systems

The Dolphin ACS is ideal for marine applications, especially outboard engine boats where reliable battery management is critical. Its advanced MOSFET technology provides superior protection for onboard electronics like GPS, fish finders, and navigation equipment by preventing voltage fluctuations during high-draw operations. The compact, solid-state design ensures years of trouble-free operation in harsh marine environments.
