Mac Plus Waterproof 48/24-30

IP67 waterproof construction

The Mac Plus Waterproof 48V brings an IP67-rated option to the Mac Plus range, allowing for installation in unenclosed environments where exposure to the elements is likely. Ideal for fishing boats, trailers, and similar applications, the Mac Plus also incorporates a new touch-safe cover to protect connections and improve durability. Boasting a sleek, contemporary finish, the robust aluminum housing further enhances resilience and reliability.

Boost batteries with bi-directional technology

Innovative bi-directional technology ensures the Mac Plus can charge both starter and service batteries by using either as an input or output and ensuring all batteries receive the charge they need. Constant monitoring and automated cut-off mean you never drain your starter battery by charging your service bank, and the Mac Plus compensates for battery temperature to deliver optimal charging performance. Parallel operation of multiple units can provide charging capacities of over 100 Amps.

Proven Mastervolt quality

The Mac Plus uses Mastervolt’s proven 3-step+ charge algorithm, delivering a quick and easy charge, even to completely flat batteries. By stabilizing the charge voltage, Mac Plus also protects your service battery and other sensitive equipment, keeping them in great working order for years to come. A power-efficient design enables the Mac Plus to operate without a fan and entirely silently, making it a practical choice for installations where noise is a concern and could potentially impact comfort and enjoyment.

Superior monitoring and control

CZone®, NMEA 2000®, and MasterBus compatibility ensure Mac Plus integrates easily into wider power systems, improves monitoring and control capabilities, and enables users to oversee and manage power functions from any display screen. On-board DIP switches and MasterAdjust, the CZone configuration tool, ensure simple and intuitive set up. 

Total power flexibility

The Mac Plus is designed for versatility. Supporting a full range of battery chemistries, including lithium, it functions seamlessly with modern alternators, delivering constant power and an efficient charge, even when the alternator is inactive. With a wide DC range, it is compatible with a broad spectrum of DC input voltages, giving you greater flexibility and putting fewer constraints on your power system. The Mac Plus also incorporates advanced modern microprocessors to ensure minimal power loss when switching from 48V/36V to 12V/24V and vice versa.
