The Mac Plus Waterproof  models offer an IP67-rated, allowing for installation in unenclosed environments where exposure to the elements is likely. Ideal for fishing boats, trailers, and similar applications, they also incorporates a new touch-safe cover to protect connections and a sleek, robust aluminium housing to further enhance resilience and reliability. Additionally, these models offer new CV Power Control mode. This exclusive feature is an optional setting that enables the Mac Plus to maintain a constant voltage (“CV”) on the starter battery, ensuring it is never drained and keeping the system operating smoothly in situations where input current may be limited.
