Description

The Mastervolt Mac Plus 48/24-30 is a DC-DC charger designed for efficient and safe charging of service batteries and providing stabilized voltage to protect sensitive equipment. It features bi-directional technology, allowing it to use either side as input or output, and delivers a reliable charge to both service and starter batteries. It utilizes Mastervolt's 3-step+ charge algorithm for quick and easy charging, even for fully flat batteries. The robust design includes high-quality aluminum housing for protection against dust and water ingress (IP23 rating) and operates silently without a fan. It supports a wide DC input range, various battery chemistries (Gel, AGM, Lithium Ion), and functions seamlessly with modern alternators (Euro 5 and 6). It also offers parallel configuration up to 4 units for increased amperage, and advanced monitoring and control via CZone, NMEA 2000, and MasterBus.
