The Victron Orion IP67 24/12-20A is a non-isolated DC-DC converter that steps a 24V DC supply down to a regulated 12V DC output, delivering up to 20A (240W). It's built for vehicles, vessels and off-grid systems where voltage conversion needs to hold up in exposed or damp locations. The IP67 enclosure means it can be mounted without hunting for a fully protected indoor spot.

Victron Orion DC-DC converter features

• Conversion, non-isolated 24V input to 12V output
• Output current, up to 20A continuous
• Output power, 240W continuous
• Protection, IP67, dust-tight and protected against temporary immersion to 1 metre
• Weight, 0.45kg

Why non-isolated topology

The Orion IP67 range uses a non-isolated buck converter, which avoids the losses that come with transformer isolation and keeps efficiency high with less heat to manage. That suits systems where the two battery banks share a common negative, such as dual-battery vehicle setups or a 24V-to-12V auxiliary supply on a boat or motorhome. Because it's non-isolated, it must not be used where galvanic isolation between input and output is required.

Applications

• Dual-battery vehicle systems running a 12V auxiliary circuit from a 24V bank
• Marine electronics, lighting or pumps fed from a 24V house bank
• Motorhomes and campervans with a 24V main system needing a 12V rail
• Off-grid cabins where a 24V bank supplies 12V loads without a second battery
• Telecoms and industrial enclosures needing sealed DC voltage conversion

Installation notes

Input and output share a common negative, so this unit isn't suitable where isolation is required. Wiring should be rated for the current involved, with fusing fitted on both input and output. Follow Victron's mounting guidance for thermal management, and have the installation carried out by someone competent with DC power systems.
