The Victron Orion 110/12-30A is a galvanically isolated DC-DC converter that steps a 110V DC input down to a regulated 12V DC output at up to 30A, giving 360W of continuous power. It suits installations where the input and output circuits must stay electrically separate, such as vehicle, marine and off-grid DC systems.

Key features

• Galvanic isolation, transformer-based separation between input and output, removing ground loop paths.
• Input, 110V DC nominal.
• Output, 12V DC at 30A continuous.
• Output power, 360W continuous.
• Weight, 1.43kg.
• Housing, fully enclosed, no moving parts.

Why isolation matters

Differences in ground potential between two DC circuits can push current through paths it was never meant to take, damaging equipment or creating a shock hazard. The Orion 110/12-30A keeps the 110V input side and the 12V output side electrically separate, which matters when a 12V load or charging circuit connects to a higher-voltage DC bus.

Applications

• Powering 12V loads or auxiliary systems from a 110V DC bus in industrial or specialist vehicles.
• Charging 12V battery banks from a higher-voltage DC source where isolation is required.
• Off-grid systems with mixed voltage architectures.
• Marine installations where isolation helps prevent stray-current corrosion.
• Telecoms and control system power supplies needing separated input and output grounds.

Installation notes

The 110V DC input is a hazardous voltage. Installation should be carried out by a qualified electrician or a competent person familiar with DC systems at this level. Fuse and size cabling on both sides to the applicable wiring regulations, and remember the input and output grounds are not connected internally.
