Mastervolt 81400100 DC Master 24/12 3-6A Non-Isolated Converter

Mastervolt 81400100 DC Master 24/12 3-6A Non-Isolated Converter

The Mastervolt 81400100 (DC Master 24/12 3-6A) is a compact, high-efficiency non-isolated DC-DC step-down converter designed to step down a 24V DC primary battery system to a stable 12V DC output. Capable of delivering up to 3A continuous current (6A peak load), this unit is engineered for running light 12V loads—such as small marine electronics, instruments, LED lighting, or communications gear—directly from 24V marine, RV, or commercial vehicle power networks.

Utilizing modern high-frequency switch-mode topology, the DC Master provides exceptional conversion efficiency (>90%), generating minimal heat within compact installations. Because this is a non-isolated model, the input and output share a common negative ground, minimizing wiring complexity and footprint while maintaining integrated protection against over-temperature, overload, short circuits, and reverse polarity.

Key Features

• High Conversion Efficiency: Switch-mode topology achieves >90% efficiency for cool operation and minimal standby drain.

• Stable Output Voltage: Delivers a steady 13.6V DC output to keep 12V electronics operating reliably despite input voltage fluctuations.

• Comprehensive Electronic Protection: Built-in safeguards against current overload, short circuits, thermal overheating, and reverse polarity.

• Compact & Lightweight Housing: Anodized aluminum housing with mounting flanges allows installation in tight helm or equipment spaces.

• Easy Installation: Shared negative ground simplifies wiring harnesses in non-isolated DC distribution systems.
