Detailed description
Detailed description
The Mastervolt Mac Plus 48/24-30 IP23 CZone is a bidirectional DC-DC converter-charger designed for 48V/24V electrical systems with a common negative ground. With a 30A output current on the low-voltage side (24V) and a power output of 720W, it stabilizes power supply for your 24V equipment from a 48V battery bank, or vice versa.
Bidirectional operation and versatility
Unlike a unidirectional DC-DC converter, the Mac Plus can reverse the current flow direction. This allows, for example, charging a 48V service battery via a 24V alternator, or boosting a 24V starter battery from the 48V bank. This function can be controlled via a remote contact, a MasterBus event, or a CZone circuit. The Mac Plus 48/24-30 differs from the 48/12-50 model in its output voltage (24V instead of 12V), and is intended for boats with a 24V network for high-power equipment (motors, thrusters, etc.).
CZone and MasterBus integration
This model is CZone-certified and MasterBus-compatible, enabling deep integration with Mastervolt energy management systems. Via the CZone network, you can configure charge profiles, set alarms, and create automation rules (e.g., load shedding in case of low battery voltage). The Mac Plus comes with a 1-meter Mastervolt-CZone connection cable and a MasterBus terminator.
Installation and protection
With an IP23 protection rating, it resists water spray and dust, making it suitable for installation in a ventilated technical compartment, away from direct spray. The package includes a battery temperature sensor to optimize charging based on temperature. Connections are made via screw terminals for cables up to 10 mm² (low side) and 6 mm² (high side).
