Victron Energy ORI241270030 Orion 24/12-70A DC-DC Converter IP20/Binding Posts

Victron Energy Orion 24/12-70A High-Power 24V to 12V Conversion Without the Bulk

Product Overview

The Victron Energy Orion 24/12-70A (ORI241270030) is a non-isolated, high-power DC-DC converter designed to step 24V battery systems down to a regulated 12V output at up to 70 amps. Built for automotive, marine, and renewable energy applications, it delivers clean, stable 12V power to 12V loads, accessories, or charging circuits running off a 24V primary bank without the weight, complexity, or cost of a galvanically isolated unit where isolation is not required.

Its adjustable output voltage makes it suitable across a range of 12V charging and load scenarios, and the ability to parallel up to five units means the Orion 24/12-70A scales with your system from a straightforward ute or camper trailer build up to high-demand commercial and marine installations needing 350A of combined 12V output. The remote on/off connector eliminates the need for high-current switching hardware, and the IP20 rating with binding post connections makes it well suited to enclosed panel, engine bay, or switchboard installations where environmental exposure is managed by the enclosure itself.

Features & Benefits

• Non-Isolated High-Power Design — Non-isolated converters share a common ground between input and output, which is appropriate for the majority of automotive, marine, and renewable energy applications where galvanic isolation is not required. The non-isolated topology delivers high efficiency and lower heat generation compared to isolated equivalents at the same power level.
• 70A Output Current — At 70A continuous output, this converter handles serious 12V loads from a 24V primary source — powering accessories, 12V battery banks, lighting circuits, audio systems, refrigeration, or communications equipment without overloading the converter.
• Adjustable Output Voltage — The output voltage is user-adjustable, making the Orion 24/12-70A suitable for a range of 12V charging profiles and load requirements beyond a fixed 12V rail — useful when matching to specific battery chemistries or load tolerances.
• Parallel Connection — Up to 5 Units — Multiple units can be connected in parallel for higher combined output current, up to 350A from five units. Each additional unit adds 70A — a clean, modular approach to scaling 12V power capacity in high-demand installations such as commercial vehicles, large marine vessels, or off-grid energy systems.
• Remote On/Off Connector — Enables the converter to be switched on and off via a low-power signal — a small toggle switch, relay output, or direct connection to the vehicle's ignition or engine run/stop circuit. Eliminates the need for high-current switching hardware in the control circuit, simplifying installation and reducing component count.
• IP20 Rated — Provides protection against solid objects greater than 12mm (fingers and similar). Suitable for installation inside enclosed panels, switchboards, engine bays with covers, or any protected indoor installation environment. Not suitable for direct exposure to water, dust, or the elements without an enclosure.
• Binding Post Connections — Large, accessible binding post terminals accommodate heavy-gauge cable appropriate for 70A continuous current. Simplifies installation in panel builds and allows for secure, low-resistance connections without specialist crimping tools.
• Low Heat Generation — High conversion efficiency means less energy is wasted as heat during operation — important in confined installation spaces where thermal management is a design constraint.

Frequently Asked Questions

What is the difference between an isolated and non-isolated DC-DC converter?

A non-isolated converter shares a common ground between input and output, making it simpler, more efficient, and lower in cost — suitable for most automotive and renewable energy applications. An isolated converter provides galvanic separation between circuits, which is required in specific marine or sensitive electronics applications.

Can multiple Orion 24/12-70A units be run in parallel for higher current output?

Yes. Up to five units can be connected in parallel, delivering a combined maximum output of 350A at 12V — a scalable solution for high-demand installations without requiring a single large, custom converter.

What does the IP20 rating mean for installation planning?

IP20 means the unit is protected against solid objects larger than 12mm but offers no protection against water or dust ingress. It must be installed inside an enclosure, switchboard, or protected panel — not exposed directly to the elements.

How does the remote on/off connector work?

The remote on/off connector allows the converter to be switched using a low-power signal — such as a small toggle switch, ignition relay, or engine run/stop output. This eliminates the need for high-current switching hardware in the control circuit, simplifying the installation significantly.

Is the output voltage fixed at 12V or can it be adjusted?

The output voltage is adjustable, allowing fine-tuning for specific charging profiles or load requirements. The exact adjustment range is not confirmed in the current supplier brief — contact us or refer to the Victron Energy datasheet for the full adjustment range.
