Detailed description
Detailed description
The Mastervolt Magic 24/24-20A DC-DC charger-converter is a high-end energy conversion solution designed for demanding marine electrical systems. Unlike standard buck or boost converters, this model provides full galvanic isolation between input and output, eliminating ground loops and protecting sensitive navigation electronics from interference. With a 20A capacity at 24V, it ensures perfectly smoothed and secure power supply, even when the main battery bank voltage fluctuates significantly due to high-load consumers.
Exceptional application versatility
The Magic 24/24-20A's main advantage lies in its operational flexibility, easily configurable via internal DIP switches. It can operate as a stabilized 27.2 VDC DC power supply, ideal for critical communication equipment. It also functions as a three-stage battery charger (Bulk, Absorption, Float), enabling fully automatic charging of a secondary 24V bank from the main 24V network. More advanced setups even allow it to be used as a dimmer for 24V lighting or wired in series to create a 24/48V conversion (without galvanic isolation in this specific mode).
Professional-grade integration and safety
Designed for advanced integration, this IP21-certified converter features an integrated alarm contact that triggers in case of undervoltage, overvoltage, overload, or short circuit, allowing the crew to be alerted or safety automations to be triggered. For higher power needs, multiple Magic units can be paralleled. Advanced users will also appreciate the QRS232 communication port, which offers the ability to finely adjust software parameters. Compared to the Mac Plus series, the Magic series stands out with its full galvanic isolation, a prerequisite for metal-hulled vessels or complex communication installations.
