Victron Orion-Tr DC-DC Converter 48/12-9A 110W

Product Description

The Victron Orion-Tr 48/12-9A 110W is an isolated DC-DC converter that safely steps down a 48 V bus to a regulated 12 V line, ideal for communications, navigation electronics, and auxiliary equipment in vehicles, marine applications, or solar installations. It offers 200 V galvanic isolation between input, output, and enclosure, IP43 protection (when mounted with terminals facing downward), and a remote on/off terminal for integration with the ignition key or a master relay. The nominal output is 12.2 V, with fine adjustment from 10 to 15 V to compensate for cable drops or adapt to sensitive loads.

Main Features

• Input range 32–70 VDC for 48 V systems; buck-boost regulation keeps the output stable within the specified range. :contentReference[oaicite:1]{index=1}
• 9 A continuous at 25 °C; 12.5 A peak (10 s). Power 110 W at 25 °C and 85 W at 40 °C. :contentReference[oaicite:2]{index=2}
• Adjustable output 10–15 V (12.2 V nominal) with 2 mV rms noise. :contentReference[oaicite:3]{index=3}
• 200 V galvanic isolation, IP43, short-circuit proof and parallelizable. :contentReference[oaicite:4]{index=4}
• Remote on/off; no-load consumption <50 mA; <200 µA when deactivated via remote port. :contentReference[oaicite:5]{index=5}
• Ultra-compact format 100×113×47 mm, 0.42 kg; terminals up to 6 mm². :contentReference[oaicite:6]{index=6}

Advantages or Benefits

• Stable 48→12 V conversion for radios, routers, cameras, or instrumentation, preventing restarts due to voltage drops.
• Clean integration with remote ignition: activate it from a contact or controller and eliminate unnecessary consumption. :contentReference[oaicite:7]{index=7}
• Professional reliability thanks to isolation, IP43, and automatic thermal derating at high temperatures. :contentReference[oaicite:8]{index=8}
• True scalability by being able to connect multiple units in parallel to increase current as the project grows. :contentReference[oaicite:9]{index=9}

Purpose or Applications

Perfect for vehicles with a 48 V battery bank powering 12 V peripherals, boats with mixed electronics, solar panels, or light industrial settings where a regulated, quiet, and safe 12 V line is required.

Technical Specifications

Data verified in the official datasheet for Orion-Tr isolated converters (110–120 W).

Compatibilities

Can be paralleled with other Orion-Tr units for higher current. Not a battery charger; for DC-DC charging use Orion-Tr Smart with charging profiles. :contentReference[oaicite:11]{index=11}

The Victron Orion-Tr 48/12-9A 110W guarantees precise, quiet, and safe 48→12 V conversion in minimal space, with the professional reliability of Victron.
