The Mastervolt Alpha Pro III is an advanced 3-step charge regulator designed to optimize the performance of standard and high-performance alternators in marine and vehicle applications. By replacing a standard alternator regulator, this device improves charging efficiency, protects against overheating and overcharging, and extends battery lifespan.

Key Features:
  • Capable of controlling alternators with outputs up to 400 A.
  • Provides full temperature-controlled 3-step charging.
  • Balances engine load to reduce RPM variations, noise, and fuel consumption.
  • Integrated keep-alive feature for accurate tachometer readings.
  • MasterBus compatible for simplified system integration and monitoring.
  • Supports high-output configurations up to 20 A field current capability.
