Detailed description
Detailed description
The Mastervolt DC Master 24/12-24 (Isolated) DC-DC converter is designed to power your 12 V equipment from a 24 V battery bank with full galvanic isolation. This model in the DC Master range delivers a continuous current of 24 A (30 A peak for 2 minutes) for a nominal power of 326 W, ensuring stable and protected power for sensitive devices (VHF, autopilot, navigation electronics).
Galvanic isolation for optimal protection
Unlike non-isolated models in the DC Master range (81400100 to 81400800), this converter features galvanic isolation between input and output circuits. This isolation eliminates ground loops and suppresses electromagnetic interference, making it ideal for sensitive equipment such as chartplotters or radios. It also supports installations with negative ground as well as positive ground configurations, offering wiring flexibility that non-isolated models do not allow.
Performance and durability
With high efficiency and standby consumption below 15 mA, this converter optimizes the autonomy of your battery bank. Its 2-minute overload capacity (30 A) is perfect for brief current draws from autopilot motors or compressors. Its anodized aluminum and glass-reinforced polycarbonate housing provides IP53 protection, making it resistant to splashes and dust. For comparison, the non-isolated 24/12-24A model (81400330) is more compact (167 mm) but does not offer galvanic isolation. This isolated model (217 mm) is the recommended choice for professional installations where power purity is critical.
Simplified installation
The DC Master 24/12-24 (Isolated) comes with a clip-on mounting bracket, screws, and faston connectors. Installation takes just a few steps: attach the bracket, clip in the converter, then connect the input wires before the output wires. Fusing the battery side is recommended. Its dimensions of 217 x 87 x 50 mm and weight of 850 g allow for discreet wall mounting in a technical compartment or electrical cabinet.
