Product Description

The Mac Plus 12/24-30 + CZone is a high-performance DC-DC charger designed specifically for marine and boating applications. It ensures your service battery receives a fast, safe, and reliable charge, even in vessels equipped with smart alternators and start/stop systems. With advanced features and robust construction, the Mac Plus is the ideal solution for maintaining your boat's electrical system.

Reliable Battery Charging for Your Marine Needs

Service batteries on boats often suffer from inadequate charging due to smart alternators and start/stop systems, which can lead to slow and insufficient charges. The Mac Plus DC-DC charger addresses this issue by delivering a consistent and rapid charge to your service battery. It intelligently detects when the engine is running, ensuring that the starter battery is never drained, providing peace of mind for boaters.

Exceptional Quality with Mastervolt Technology

Experience the superior quality of Mastervolt with the Mac Plus charger. Utilizing the proven 3-step+ charge algorithm, it efficiently charges even completely flat batteries. The charger features a durable aluminum housing that protects against dust and water ingress, making it perfect for the harsh marine environment. Additionally, the fanless design ensures silent operation, maintaining the tranquility of your boat.

Key Features:

  • Fast and safe charging, even during short trips
  • Fanless design for silent operation
  • Compatible with flooded, Gel, AGM, and Li-Ion batteries, including LiFePO4
  • Efficiently charges fully depleted batteries
  • Engine run detection to protect the starter battery
  • Adjustable current limits for Euro 5/6 compliance
  • Voltage stabilization to protect sensitive equipment and lights
  • Parallel operation capability to achieve over 100 Amps
  • Compatible with MasterBus, CZone, and NMEA 2000 for intelligent system monitoring and automation
  • Temperature compensation and voltage sensing for optimal charging
