Victron Energy ORI121240110 360W 12/12-30A Orion-Tr Isolated DC-DC Converter
360W Galvanically Isolated 12V-to-12V DC-DC Converter 87% Efficient, Remote On/Off, Parallel-Capable, Built for Dual Battery and Marine Applications.
Product Overview
The Victron Energy Orion-Tr 12/12-30A (ORI121240110) is a 360W galvanically isolated DC-DC converter that steps and stabilises a 12V DC input to a regulated 12V DC output delivering 30A of continuous output current with 87% conversion efficiency. Galvanic isolation of 200V DC between input, output, and case makes it the correct solution wherever electrical separation between two battery banks is required preventing ground loops, protecting sensitive electronics, and providing a stable, noise-free output (2mV RMS) for charging and powering sensitive loads.
Designed as a true worldwide product, the Orion-Tr suits dual battery systems in 4WDs, caravans, and marine vessels, as well as vehicle-to-vehicle charging and battery-to-battery charging in any 12V installation where a galvanically isolated, regulated DC source is preferred over a direct battery connection. Output voltage is adjustable from 10V to 15V enabling use as a precision battery charger for 12V starter or auxiliary batteries. Remote on/off eliminates the need for a high-current switch in the input wiring, allowing control via a low-power switch or the vehicle's engine run/stop signal.

Features & Benefits
- 200V DC Galvanic Isolation — Full electrical isolation between the input battery, output circuit, and the converter case prevents ground loops, eliminates noise coupling between battery banks, and protects sensitive downstream electronics. Essential in marine installations where ground loop corrosion is a risk, and in dual battery systems where complete electrical separation between the primary and auxiliary battery is required.
- 2mV RMS Output Noise — Exceptionally low output noise for a DC-DC converter — critical for powering sensitive electronics, audio systems, instruments, and communications equipment from a vehicle battery without introducing electrical interference.
- Adjustable Output Voltage (10V – 15V) — The adjustable output range allows the Orion-Tr to be configured as a precision battery charger — for example, charging a 12V starter battery or accessory battery from a 12V primary battery system. Fine-tune the output to match specific battery chemistry requirements.
- 30A Continuous / 40A Peak (10s) — 30A of continuous output at 25°C with a 40A 10-second peak handles the start-up surge of heavy loads without tripping. Short-circuit output is rated at 60A, and the unit is fully short-circuit proof.
- 87% Conversion Efficiency — At 87% efficiency, the Orion-Tr converts the majority of input power to useful output — minimising heat generation and reducing the load on the source battery compared to lower-efficiency alternatives.
- Thermal Derating with High-Temperature Protection — Rather than shutting down under high ambient temperatures, the Orion-Tr progressively reduces output current — 3% per °C above 40°C — keeping the converter operational through Australian summer conditions while protecting its components. Continuous output at 40°C is rated at 360W.
- Remote On/Off — A dedicated remote on/off input eliminates the need for a high-current switch in the input wiring. A simple low-power switch or the vehicle's engine run/stop signal can control the converter — a clean installation solution for systems that should only operate when the engine is running.
- Parallel Operation — Unlimited Units — Multiple Orion-Tr units can be connected in parallel to increase total output current — with no confirmed limit on the number of parallel units. Scale output capacity to match system requirements without replacing the converter.
- IP43 (Terminals Downward) — IP43 protection is achieved when the unit is installed with screw terminals oriented downward — protecting against solid object ingress and water spray at 60° from vertical. Installation orientation is a firm requirement to achieve the stated IP rating.
- Screw Terminal Connections — No crimping tools or special connectors required. The maximum cable cross-section of 16mm² (AWG 10) supports appropriate high-current wiring for the 30A output rating.
- Built-In Non-Replaceable Input Fuse — Provides internal overcurrent protection on the input side. As the fuse is not field-replaceable, a blown fuse indicates a fault condition requiring service.

Frequently Asked Questions
What does galvanic isolation mean and why does it matter?
Galvanic isolation means there is no direct electrical connection between the input and output circuits. In this unit, 200V DC isolation exists between the input battery, output circuit, and the converter case. This prevents ground loops, eliminates electrical noise coupling between battery banks, protects against corrosion in marine installations, and allows the output circuit to float independently of the input ground reference.
Can the Orion-Tr be used to charge an auxiliary battery while driving?
Yes. The adjustable output voltage (10V–15V) allows the Orion-Tr to be configured as a battery charger — delivering a regulated charging voltage to the auxiliary battery from the vehicle's alternator/primary battery while driving. Use the remote on/off input to tie operation to the engine run signal so charging only occurs when the alternator is active.
What does the thermal derating mean in practice?
Above 40°C ambient, the Orion-Tr reduces its output current by 3% per additional degree Celsius. At 55°C (the maximum operating temperature), output is reduced to approximately 55% of the rated 30A. The converter remains operational throughout — it does not shut down. This is the reason the product title references 360W (the 40°C rating) rather than the 430W figure which applies only at 25°C.
Can multiple Orion-Tr units be paralleled for higher output current?
Yes. Victron confirms that an unlimited number of units can be paralleled to increase total output current. Ensure consistent input wiring and fusing across all units when paralleling. Refer to the Victron Orion-Tr installation manual for correct parallel wiring configuration.
What is the IP43 rating and does the installation orientation matter?
IP43 provides protection against solid objects greater than 1mm and water spray up to 60° from vertical. This rating is only achieved when the unit is installed with screw terminals oriented downward — a specific installation requirement confirmed by Victron. Installing in a different orientation may reduce effective ingress protection.
