Mastervolt Mac Plus Waterproof — New IP67 Waterproof DC-DC Chargers

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.

Innovative bi-directional technology ensures the Mac Plus can charge both starter and service batteries by using either side 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.

CV (Constant Voltage) Power Control mode, an optional setting exclusive to Mastervolt, enables the Mac Plus to maintain a constant voltage on the starter battery, ensuring it is never drained and keeping the system operating smoothly in situations where input current may be limited.
