Victron Energy Orion 24/12V 70A DC-DC Converter — High-efficiency, Remote On/Off

Victron Energy Orion 24/12-Volt 70 amp DC-DC Converter converts 24V vehicle systems to a regulated 12V, delivering up to 70A for accessories and auxiliary batteries.

The Orion 24/12-70A is a high-efficiency DC‑DC step‑down converter built for vehicles, boats, RVs and other 24V installations that need a stable 12V supply. It stabilizes voltage, protects against system fluctuations and can serve as a dedicated battery charger or a power feed for sensitive 12V electronics. Designed for flexible installation, the unit includes remote on/off capability and adjustable output models that expand its uses in multi-battery systems.

How does the Orion keep 12V devices safe on a 24V system?

The Orion provides regulated 12V output that isolates and stabilizes downstream electronics from voltage spikes, engine alternator surges and 24V system variation. Its internal design reduces the risk of under- or over-voltage to attached devices and batteries.

• Regulates input to a steady 12V output suitable for sensitive electronics.
• High-efficiency conversion minimizes heat and energy loss.
• Protection features guard against common automotive electrical events.

Can I use this converter to charge a 12V starter or accessory battery?

Yes — models with an adjustable output setting can act as a DC battery charger for a 12V starter or auxiliary battery in a 24V system. The adjustable output lets you set an appropriate charging voltage and current for different battery chemistries.

• Adjustable output converts the unit into a controlled 12V charger.
• Suitable for charging starter, accessory, or deep‑cycle 12V batteries.
• Use proper charging profile and cabling consistent with battery manufacturer guidance.

How do I control or switch the Orion remotely?

The converter includes a remote on/off connector so you don’t need a heavy-duty inline switch in the main input feed. That lets you operate the unit with a low-current switch or link its control to an engine run/stop circuit for automatic behavior.

• Remote on/off allows low-current switches to control the converter.
• Integrate with engine run/stop or accessory control for automatic switching.
• Reduces complexity and cost by avoiding a high-current input switch.

What if I need more output current than 70A?

Multiple adjustable-output Orion units can be paralleled to boost total available current. Victron permits up to five matching units in parallel when configured correctly, offering a scalable solution for heavier loads.

• Parallel up to five adjustable-output units for greater total amperage.
• Ensure identical model and settings for safe paralleling.
• Use appropriate fusing and wiring practices when combining units.

Who is this for: The Victron Orion 24/12‑70A is aimed at installers and owners of commercial or recreational 24V platforms who need a dependable 12V source — mechanics wiring starter/accessory batteries, boat owners adding electronics, RVers powering appliances, and fleet or off-grid systems requiring a stable 12V supply. It’s especially useful where remote switching, adjustable charging, or scalable output is required. Follow Victron’s installation guidance, use proper cable sizing and fusing, and match the converter settings to your battery specifications for best results.
