Victron Orion-Tr DC-DC Converter 12/48-8A 380W

Product Description

The Victron Orion-Tr 12/48-8A 380W is a high-performance isolated DC-DC converter that enables the creation of a stable 48 V line from a 12 V battery bank, which is essential when powering professional electronics (radio links, industrial routers, PLCs, 48 V lighting, or instrumentation). Its robust chassis, 200 V galvanic isolation between input, output, and casing, IP43 protection, and remote on/off terminal ensure safe, silent, and efficient integration in vehicles, marine applications, campers, and mobile solar energy systems. The output voltage is adjustable, so you can set the line to 48.2 V or fine-tune it within the 40–60 V range to compensate for cable drops or sensitive equipment requirements. :contentReference[oaicite:0]{index=0}

Main Features

• 8 A continuous at 48 V with a reference power of 380 W at 40 °C and up to 430 W at 25 °C (Orion-Tr 360–400 W family). :contentReference[oaicite:1]{index=1}
• Input range specific to the 12 V series models: 10–17 V, with buck-boost regulation to keep the output stable. :contentReference[oaicite:2]{index=2}
• Adjustable output 40–60 V (48.2 V nominal) to adapt the line to equipment or long cable runs. :contentReference[oaicite:3]{index=3}
• 200 V galvanic isolation, IP43 protection (installation with terminals facing down), and noise level of only 2 mV rms. :contentReference[oaicite:4]{index=4}
• Remote on/off; no-load consumption <100 mA and <200 µA when deactivated remotely. :contentReference[oaicite:5]{index=5}
• Can be paralleled (unlimited number), short-circuit proof, and with automatic thermal derating. :contentReference[oaicite:6]{index=6}

Advantages or Benefits

• Safely converts from 12 V to 48 V, protecting sensitive electronics and preventing restarts due to voltage drops.
• Simple master control: the remote on/off terminal allows integration with key contact, relays, or controllers without installing power switches. :contentReference[oaicite:7]{index=7}
• Professional reliability in demanding environments thanks to isolation, IP43, over-temperature protection, and short-circuit proof design. :contentReference[oaicite:8]{index=8}
• True scalability: you can connect multiple units in parallel to increase the total current available at 48 V as the project grows. :contentReference[oaicite:9]{index=9}
• Clean installation with screw terminals and large admissible section, reducing losses in long runs and facilitating maintenance. :contentReference[oaicite:10]{index=10}

Purpose or Applications

Designed for intervention vehicles and campers that require 48 V loads, vessels with bridge electronics or 48 V communications, CCTV/IoT systems and radio links, networks, and light industrial automation. In off-grid solar, it is perfect when the main battery bank is 12 V but you want to power telecommunications equipment at 48 V in a stable manner.

Technical Specifications

Data consolidated from the official datasheet of Orion-Tr isolated converters (360–400 W tables).

Compatibilities

Can be connected in parallel with other Orion-Tr units to increase the current at 48 V. It is not a battery charger; for DC-DC charging from 12 V use the Orion-Tr Smart range with specific charging profile. :contentReference[oaicite:12]{index=12}

The Victron Orion-Tr 12/48-8A 380W offers precise, silent, and safe 12→48 V conversion, with fine voltage adjustment, galvanic isolation, and the professional reliability characteristic of Victron for demanding projects.
