12V Adjustable External Voltage Regulator for Marine Alternator Charging Systems

Provides external P-Type alternator regulation for 12 V marine electrical systems, with adjustable target charging voltage to accommodate different battery technologies and manufacturer charging requirements. The regulator is factory set to a 14.1 V target voltage, which can be raised or lowered through the onboard adjustment potentiometer. Dedicated power, ignition, field, stator, ground and undervoltage sensing connections support integration with compatible alternator charging systems, while colour-coded indicator LEDs provide visual status information for regulator power, stator activity, field output and low battery voltage. A tachometer output also provides an AC signal for compatible electrical tachometers.

Key Features

• 12 V External Regulation: Provides P-Type external field control for compatible 12 V marine alternators.
• Adjustable Target Voltage: Allows the maximum charging voltage to be adjusted according to battery manufacturer requirements.
• 14.1 V Factory Setting: Supplied with the target charging voltage preset to 14.1 V.
• Voltage Adjustment Potentiometer: Enables charging voltage to be raised or lowered directly at the regulator.
• Battery Voltage Sensing: Uses dedicated voltage sensing to monitor positive battery voltage during operation.
• Stator Input: Receives voltage input from the alternator AC stator circuit for operating status monitoring.
• Tachometer Output: Provides an AC voltage signal for connection to a compatible electrical tachometer.
• Four Status Indicators: Green, red, yellow and orange LEDs provide visual indication of regulator power, stator activity, field output and undervoltage status.
• Undervoltage Warning: The orange indicator illuminates when battery voltage falls below 12.8 V while the regulator is operating.
• Wiring Harness: Includes the wiring required for standard power, ignition, field, stator and ground connections.

Enabling direct adjustment of charging voltage, the regulator provides a straightforward method of matching compatible alternator output to 12 V battery charging requirements. Its integrated status indicators and dedicated sensing connections also assist with system monitoring and troubleshooting.
