Mastervolt DC Master 24-12 12A

Mastervolt DC Master — 24V to 12V DC Converter, 12A Output

Compact step-down DC converter for vehicle and marine builds running a 24V main system but needing 12V for smaller loads like fridge, lights, USB outlets, and accessories.

Key Features

• 24V input → 12V output (isolated)
• 12A continuous output — enough for fridge, lighting circuits, and small device loads
• 98% efficiency — very little heat generated
• Reverse polarity, over-temperature, and short-circuit protection
• Compact form factor for space-constrained installs

Use Cases

• Class B RVs and Sprinter/Transit builds with 24V OEM systems running 12V aftermarket accessories
• Off-grid cabins with 24V solar banks needing 12V circuits for DC lighting/fans
• Commercial van fleet conversions with mixed-voltage requirements
