Mastervolt 81500200 DC Master 24/12 6-10A Isolated

Mastervolt 81500200 DC Master 24/12 6-10A Isolated Converter

The Mastervolt 81500200 (DC Master 24/12 6-10A Isolated) is a high-reliability galvanically isolated DC-DC step-down converter designed to convert a 24V DC primary battery bank to a clean, stable 13.6V DC output. Capable of supplying 6A continuous current and up to 10A peak boost load (2-minute duty), this converter is engineered to power sensitive 12V marine navigation electronics, radio equipment, and sensor suites directly from a 24V electrical system.

Featuring complete electrical separation between the input and output circuits, the isolated design prevents ground loops, eliminates stray current corrosion, and filters out high-frequency electrical noise from motors and alternators. The unit supports both positive and negative earthing configurations, making it suitable for alloy/steel hull vessels and sensitive electronic systems requiring isolated power domains. 

Key Features

• Galvanic Isolation: Complete electrical separation between input and output prevents ground loops, reduces radio interference, and protects sensitive marine gear.

• 2-Minute Power Boost: Delivers up to 10A peak power for short-term high-demand startup loads.

• Clean, Stabilized Output: Provides a constant 13.6V DC output to ensure consistent performance despite primary battery voltage fluctuations.

• Flexible Grounding: Compatible with both negative and positive earthing systems.

• Quiet & Efficient: Compact switch-mode architecture with natural convection cooling provides silent operation without internal fans.
