Sterling Pro Reg BW Waterproof Alternator Regulator 12V

Standard alternators are not designed to be good battery chargers, their flat voltage outputs make alternators inherently bad at recovering auxiliary battery banks. With a ProRegB Regulator you can convert the constant voltage output of a standard vehicle’s alternator into a 4- stage progressive constant current battery charging profile. This high performance, marine grade alternator regulator recovers your house battery bank five times faster than using just a standard alternator!

• Includes temperature sensor with 1 metre of cable
• Digital software control with slow start
• Dynamic Progressive battery charging
• Can be used in parallel ( recommended ) or stand-alone regulator
• Programmable for different battery types
• Single unit fits 99% of alternators and all battery types
• Charges to 4 step progressive constant current charging curves
• Self-diagnosing fault system
• Totally isolates the advanced regulator in fault condition
• Information 8 LED display
• Battery Temperature sensing
• High battery temp trip
• High battery voltage trip
• High alternator voltage trip
• De-sulphating ability on open lead acid batteries
• In event of failure auto return to standard alternator regulator
• Can be used with or without the temperature sensor
• Monitors for excessive neg voltage drop and trips
• Protects batteries if temperature sensor open circuited
• Protects batteries if split charge relay/diode fails open
• Protects batteries if advanced reg fails closed
• Protects batteries if battery sense wire falls off
Please note that advanced regs are not suitable for modern vehicles/boats with integrated engine management systems as they increase the alternators voltage and this can be interpreted by the management system as a fault on the alternator. Please use an alternator to battery charger or battery to battery charger for these applications.
