What is a DC-DC Converter?
A DC-DC converter is an essential power electronics device that takes a direct current (DC) input voltage and provides a regulated DC output voltage. The output voltage can be either higher or lower than the input voltage, depending on the system’s needs.
Why Use a DC-DC Converter?
- Provides a stable and constant power supply to sensitive electronics and devices.
- Allows you to power devices with different voltage requirements from the same system. For example, run a 12V pump on a 48V system safely and efficiently.
- Supports dual battery setups in RVs, marine systems, off-grid solar, and commercial vehicles.
- Equipped with safety protections like short circuit resistance, under-voltage shutdown, and thermal protection.
Whether you’re upgrading your off-grid system, boat, RV, or commercial setup — a DC-DC converter ensures reliable and efficient power management across multiple voltage levels.

Victron Orion-Tr 48V to 12V DC-DC Converter FAQ
A DC-DC converter changes one DC voltage level to another, either stepping up or stepping down voltage, and provides a regulated, stable output to run electronic devices or charge batteries.
You need a DC-DC converter if your system requires stable voltage conversion, especially when running 12V devices from a 24V or 48V power source, or for dual battery setups in RVs, boats, and off-grid applications.
Victron Orion DC-DC converters are designed to provide regulated DC power to DC loads and auxiliary battery banks in vehicles, boats, and off-grid systems. They are programmable, temperature-protected, and short-circuit proof.
Yes. A DC-DC charger is highly recommended for lithium batteries, especially if your vehicle uses a smart alternator or if you're charging AGM or lithium auxiliary batteries from the vehicle alternator.
Yes. The Orion-Tr DC-DC converter has an adjustable output voltage range of 10-15 V using a built-in potentiometer. Always adjust the voltage before connecting batteries or paralleling units.
The Orion-Tr is short circuit proof, high-temperature protected (reducing current at high temperatures), and offers galvanic isolation between input and output for safe and reliable operation.
Yes, the Orion-Tr is designed for professional use in RVs, camper vans, marine dual-battery setups, off-grid solar systems, and heavy-duty trucks.
Yes. Multiple units can be connected in parallel to increase output current capacity. Be sure to set the output voltage before parallel installation.
The input voltage range is from 32 to 70 V, designed for use in 48V systems.
Although the output is adjustable, Victron recommends using the Orion-Tr Smart DC-DC Charger for dedicated battery charging, as it offers advanced charging algorithms.
The maximum continuous power output at 40°C is 240W.
Yes. The output voltage can be adjusted between 10 to 15 V using the built-in adjustment screw.
Yes, multiple units can be connected in parallel to increase total output current. Each unit should be configured correctly before parallel installation.
