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.
