Victron Orion-Tr DC-DC Converter 48/24-5A 120W

Product Description

The Victron Orion-Tr 48/24-5A 120W is an isolated DC-DC converter designed to generate a regulated 24 V line from 48 V systems with maximum reliability. Its 200 V galvanic isolation between input, output, and enclosure protects connected electronics, while the IP43 protection rating ensures reliable operation in mobile applications if installed with terminals facing downward. The nominal output voltage is 24.2 V and can be adjusted between 20 and 30 V to compensate for voltage drops or adapt to specific equipment, maintaining a very low noise level (2 mV rms). :contentReference[oaicite:12]{index=12}

Main Features

• 32–70 VDC input suitable for 48 V battery banks; undervoltage 28 V and restart 30 V. :contentReference[oaicite:13]{index=13}
• 5 A continuous; 6.3 A peak (10 s); power 120 W at 25 °C and 110–115 W at 40 °C.
• Adjustable output 20–30 V (24.2 V nominal), tolerance ±0.2 V and noise 2 mV rms. :contentReference[oaicite:15]{index=15}
• 200 V isolation, IP43, short-circuit proof and parallelizable to increase current if necessary. :contentReference[oaicite:16]{index=16}
• Remote on/off; no-load consumption <60–80 mA; deactivation <200 µA. :contentReference[oaicite:17]{index=17}
• Ultra-compact format 100×113×47 mm and 0.42 kg; terminals up to 6 mm² for clean wiring in confined spaces. :contentReference[oaicite:18]{index=18}

Advantages or Benefits

• Precisely stabilizes 24 V power supply from a 48 V battery bank, preventing reboots of radios, routers, cameras, PLCs, and LED lighting.
• Simple integration via the remote start terminal: allows control of the converter from the ignition switch or a master relay. :contentReference[oaicite:19]{index=19}
• Professional protection and reliability thanks to galvanic isolation, IP43, and thermal management with automatic power reduction. :contentReference[oaicite:20]{index=20}
• True scalability with parallel connection of multiple units when the project requires higher current at 24 V. :contentReference[oaicite:21]{index=21}
• Quick and tidy installation in marine lockers, vehicle panels, and communication cabinets due to its size and screw terminals.

Purpose or Applications

Recommended for intervention vehicles and campers with 24 V electronics powered from 48 V battery banks, boats with mixed loads, and solar/industrial systems that require a quiet and regulated 24 V line.

Technical Specifications

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

Compatibilities

Can be connected in parallel with other Orion-Tr units to increase current. Not a battery charger; for DC-DC charging use Orion-Tr Smart with charging profiles. :contentReference[oaicite:23]{index=23}

The Victron Orion-Tr 48/24-5A 120W provides precise, quiet, and safe 48→24 V conversion in a minimal size, ideal for mobile and industrial projects that demand professional reliability.
