The Victron Orion 24/12-80 is a non-isolated DC-DC converter that steps a 24V DC input down to a regulated 12V DC output, delivering up to 80A. It suits professional installations where a 24V system needs to run 12V loads or top up a 12V auxiliary battery, including commercial vehicles, marine vessels and off-grid setups with mixed-voltage wiring.

Key features of this Victron DC-DC converter

• Conversion, non-isolated 24V to 12V step-down.
• Output current, up to 80A.
• Enclosure rating, IP20, for protected indoor or cabinet installation.
• Weight, 0.9kg.
• Compatibility, works alongside Victron battery monitors, inverters and charge controllers.

Product overview

This is a non-isolated buck converter, so input and output share a common ground. That keeps the unit efficient and compact but means grounding needs care during installation. Where galvanic isolation is needed between circuits, a different converter variant is the better choice.

Victron's Orion range is used widely by installers in marine, automotive and off-grid work, and the 24/12-80 sits at the higher-output end of the non-isolated line-up compared with the smaller models in the series.

Applications

• Powering 12V loads from a 24V house battery bank in motorhomes, coaches or HGVs.
• Charging a 12V auxiliary battery from a 24V primary bank on marine vessels.
• Supplying 12V control circuits or accessories in off-grid cabins and industrial sites with 24V infrastructure.
• Dual-voltage systems where a 24V inverter or battery bank needs to feed 12V equipment.
• Telecom and remote monitoring enclosures needing a regulated 12V rail from a 24V supply.

Installation notes

Fit this converter in a dry, ventilated, enclosed location in line with its IP20 rating. As a non-isolated unit, input and output share a common ground reference, and incorrect grounding can cause faults or damage connected equipment. Installation should be carried out by a qualified electrician familiar with DC power systems, with appropriate fusing fitted on both input and output circuits to match the wire gauge and rated current.
