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

Product Description

The Victron Orion-Tr 48/48-8A 380W is an isolated DC-DC converter designed to maintain a perfectly regulated 48 V line when the source system also operates at 48 V. Thanks to its galvanic isolation architecture of 200 V between input, output, and enclosure, and its IP43 protection, it offers clean and safe power even in mobile environments (vehicles, marine, campers) or industrial settings. The nominal output is 48.2 V and can be adjusted between 40 and 60 V to compensate for voltage drops in long cabling or to adapt to specific requirements of sensitive electronics. It incorporates a remote on/off terminal for integration with contactors, relays, or the vehicle's own ignition, reducing standby consumption and simplifying system control.

Main Features

• 40–70 VDC input (48 V systems) with buck-boost regulation that keeps the output voltage stable within the specified range. :contentReference[oaicite:1]{index=1}
• 8 A continuous at 40 °C; 15 A peak (10 s); power 380 W at 40 °C and 430 W at 25 °C. :contentReference[oaicite:2]{index=2}
• Adjustable output 40–60 V (48.2 V nominal), tolerance ±0.2 V and output noise 2 mV rms to protect critical electronics. :contentReference[oaicite:3]{index=3}
• IP43 protection (terminals facing down), short-circuit proof and parallelizable to increase current. :contentReference[oaicite:4]{index=4}
• Remote on/off; typical no-load current <80 mA and <200 µA when deactivated via the remote port. :contentReference[oaicite:5]{index=5}
• Professional chassis 130×186×70 mm; weight approx. 1.6 kg; screw terminals up to 16 mm² (AWG6). :contentReference[oaicite:6]{index=6}

Advantages or Benefits

• 48 V stability in networks with fluctuations: prevents reboots of radio links, switches, routers, PLCs, and 48 V luminaires.
• Simple integration with the system: remote ignition allows it to be controlled from the ignition, a relay, or an external controller, minimizing standby consumption. :contentReference[oaicite:7]{index=7}
• Professional reliability thanks to galvanic isolation, IP43, and thermal management with automatic power reduction at high temperatures. :contentReference[oaicite:8]{index=8}
• True scalability: possibility to connect multiple units in parallel to increase the available current at 48 V without complexity. :contentReference[oaicite:9]{index=9}
• Clean installation in panels and technical enclosures with large-section terminals that reduce losses in long runs.

Purpose or Applications

Recommended for industrial and emergency fleets, vessels with extensive 48 V electronics, data links and video surveillance (CCTV/IoT), light automation, and off-grid solar installations where a consistently stable 48 V line is needed with higher current than the 2.5 A or 6 A versions.

Technical Specifications

Values verified in the official datasheet of Orion-Tr isolated 360–400 W.

Compatibilities

Allows parallel connection with other Orion-Tr units to increase available current. It is not a battery charger; if DC-DC charging is needed, use the Orion-Tr Smart range with specific charging profiles. :contentReference[oaicite:11]{index=11}

The Victron Orion-Tr 48/48-8A 380W ensures powerful, quiet, and safe 48 V power supply, with fine adjustment and professional integration for the most demanding communications and control applications.
