Victron Orion-Tr DC-DC Converter 48/48-6A 280W

Product Description

The Victron Orion-Tr 48/48-6A 280W is an isolated DC-DC converter designed to maintain a robust 48 V line when the system bus is also 48 V but there are load peaks, voltage drops due to distance, or disturbances that could affect electronics. With 6 A continuous (280 W reference) and an output adjustable between 40 and 60 V, it ensures stable power supply for radio links, switches, routers, PLCs, sensors, and 48 V luminaires. Its professional construction includes 200 V galvanic isolation between input, output, and enclosure, IP43 protection rating, and a remote on/off terminal for control via contact, relay, or controller. It is the ideal option when the project demands reliability, electrical silence, and a solid, easy-to-wire format.

Main Features

• 48 V input (typ. 32–70 V) with buck-boost regulation.
• 6 A continuous; 280 W power at 40 °C and ~320 W at 25 °C; peak ~8 A (10 s).
• Adjustable output 40–60 V (48.2 V nominal) with noise around 2 mV rms.
• 200 V galvanic isolation, IP43, short-circuit protection, and automatic thermal derating.
• Remote on/off with reduced idle consumption and deactivation mode (<200 μA).
• Chassis 130×186×70 mm; ~1.3 kg; screw terminals up to 16 mm² for long, low-loss runs.

Advantages or Benefits

• Keeps 48 V stable for critical electronics, minimizing restarts and errors due to voltage drops.
• Facilitates centralized system control with remote switching and avoids unnecessary standby consumption.
• Robustness and safety in demanding environments (vehicles, marine, light industry) thanks to isolation and IP43 protection.
• Scalable: possibility to connect multiple units in parallel when the project requires higher total current.
• Professional and tidy installation with large-section terminals and a housing suitable for technical panels.

Purpose or Applications

Recommended for vehicles and boats with extensive 48 V electronics; telecommunications, IoT, or video surveillance panels; and off-grid solar systems that require a stabilized 48 V voltage with higher current than the 2.5 A version.

Technical Specifications

Compatibilities

Supports parallel operation with other Orion-Tr units to increase available current. Not a battery charger; for DC-DC charging use Orion-Tr Smart with charging profiles.

The Victron Orion-Tr 48/48-6A 280W provides powerful, quiet, and safe 48 V stabilization, with fine adjustment and the professional reliability required by modern mobile and industrial applications.
