The Mastervolt DC Master 6A is a compact DC-DC voltage converter that steps down 20–32V DC input to a stable 12V DC output at 6A continuous. Designed for recreational and semi-professional marine use, it allows 24V vessel systems to power 12V electronics and accessories without a separate battery bank or inverter.
The DC Master includes a mounting bracket for straightforward installation and delivers surge power for two-minute intervals — making it well-suited for active marine VHF radio and telephone use where brief power peaks are required. A reliable, space-efficient solution for mixed-voltage marine electrical systems.
