Mastervolt DC Master 24/12 12-18A Isolated Converter 81500300

Mastervolt DC Master 24/12 12–18A Isolated DC-DC Converter (81500300)

The Mastervolt DC Master 81500300 is an isolated 24V to 12V DC-DC Voltage Converter engineered to step down 24V DC battery power to a stable, clean 13.6V DC output for 12V onboard electronics, navigation systems, and lighting. Delivering a continuous current output of 12 A and a peak short-term capacity of 18 A, it safeguards sensitive equipment against voltage fluctuations, spikes, and electrical noise.

Featuring complete galvanic isolation between the input and output circuits, the 81500300 prevents ground loops, reduces stray current corrosion risks, and eliminates radio frequency interference (RFI) on marine VHF and communication channels. Encased in a rugged, anodized aluminum IP53 housing, it includes integrated protection against overload, over-temperature, short-circuiting, and reverse polarity.

Key Features

• Galvanic Isolation: Electrically isolates input and output circuits to suppress RFI noise, eliminate ground loops, and prevent stray-current hull corrosion.

• Stable Power Output: Supplies a constant 13.6 V DC output even during primary battery voltage drops or alternator charging spikes.

• 12 A Continuous / 18 A Peak Rating: Safely drives moderate continuous DC loads and handles brief inductive motor inrush currents.

• Compact & Rugged Anodized Housing: IP53 weather-resistant aluminum casing withstands high vibration, moisture, and engine room heat.

• Comprehensive Protection Suite: Built-in safeguards against thermal overload, output short circuits, over-voltage, and reverse polarity.
