Description
Alternator Temperature Sensor
The Mastervolt Alternator Temperature Sensor (Product Code: 41500400) is an essential safety component designed specifically to protect marine alternators from overheating. It feeds real-time thermal data back to a compatible regulator, allowing the system to dynamically scale back the charging current if temperatures approach dangerous limits.
Technical Specifications
- System Compatibility: Exclusively integrates with the Mastervolt Alpha Pro III 3-Step Charge Regulator (Part Number: 45513000).
- Alternator Use: Provides critical over-temperature protection, especially when using high-output or non-Mastervolt alternators.
- Connection Interface: Features an RJ11 plug connector with a 6-foot (2-meter) cable.
- Hardware Profile: Equipped with a 5/16-inch lug hole designed to bolt directly to the frame or casing of the alternator.
Strategic Installation & Function
The sensor must be securely fastened to the metal housing of the alternator. Because high-output alternators run hot when charging heavy battery banks, the Alpha Pro III regulator relies on this sensor to automatically dial down the field current before thermal runaway occurs.
