Victron Orion-Tr 48/24-16A Isolated DC-DC Converter: Clean, Stable Power for Sensitive Electronics

Galvanic Isolation for Superior Noise Rejection and System Protection

The Victron Orion-Tr 48/24-16A delivers a regulated, isolated DC output, making it the ideal solution for powering sensitive loads where electrical noise and ground loops cannot be tolerated. Unlike non-isolated converters, this unit provides 200V DC galvanic isolation between input, output, and case, effectively breaking ground loops and suppressing interference. This is critical for marine electronics, communications equipment, and industrial sensors where signal integrity is paramount.

With a wide input voltage range of 40-70V, it maintains a stable output even when the source voltage fluctuates, protecting your equipment from brownouts and surges. The output voltage is fully adjustable from 20-30V, allowing precise matching to your load requirements.

Engineered for Demanding Environments

Built on Victron's proven Orion platform, this converter features a rugged, compact design with an IP43 protection rating when installed with terminals facing downwards. The fully potted electronics and conformal-coated PCB resist moisture, dust, and vibration, ensuring long-term reliability in off-grid solar systems, vehicle-based installations, and marine engine rooms.

Passive cooling via an integrated aluminium heatsink eliminates noisy fans and moving parts, reducing maintenance and points of failure. The wide operating temperature range of -20 to +55°C (derating above 40°C) ensures consistent performance across Australia's diverse climates, from the tropical north to the arid interior.

Key Features

• Galvanic isolation (200V DC) between input, output, and case eliminates ground loops and protects sensitive electronics
• Wide input voltage range (40-70V) with under-voltage shutdown and restart for battery protection
• Adjustable output voltage (20-30V) for precise load matching
• Remote on/off control via low-power switch eliminates need for high-current input wiring switch
• Short circuit proof and capable of unlimited parallel connection for higher current demands
• High efficiency up to 89% reduces heat generation and wasted energy
• IP43 protection when installed with terminals downwards, suitable for harsh environments
• Compact and lightweight design with integrated heatsink for fanless operation
• Screw terminals accept cables up to 16 mm² for secure, low-resistance connections

Applications Where Clean Power Matters

This isolated DC-DC converter excels in scenarios where voltage stability and noise immunity are non-negotiable:

• Marine electronics: Power navigation systems, autopilots, and communication radios without interference from engine alternators or inverters.
• Caravans and RVs: Provide stable 24V to sensitive appliances like compressor fridges, LED lighting, and entertainment systems, regardless of battery voltage sag.
• Off-grid solar systems: Step voltage down from 48V to 24V between battery banks of different voltages, or supply clean power to monitoring and control equipment.
• Industrial and laboratory equipment: Isolate sensitive measurement instruments from noisy DC bus voltages in factories or test benches.
• Telecommunications: Ensure reliable operation of remote radio repeaters and networking gear with a regulated, isolated supply.

Why Choose an Isolated Converter?

Standard non-isolated DC-DC converters share a common ground between input and output, which can introduce electrical noise, ground loops, and potential damage to sensitive electronics. The Victron Orion-Tr isolated series breaks this connection, providing a 'floating' output that is electrically independent. This is especially important in vehicles and boats where multiple charging sources and varying ground potentials can cause erratic behaviour in connected devices.

Additionally, the adjustable output voltage allows this converter to be used as a constant voltage power supply for equipment that requires a specific voltage, such as LED lighting systems or certain telecommunications gear. Note: This unit is a DC-DC converter, not a multi-stage battery charger. For battery charging applications, see the Victron Orion-Tr Smart Charger range.

Installation and Integration

Installation is straightforward with clearly labelled screw terminals and a removable green remote on/off connector. The remote port can be wired to a vehicle's ignition switch, a manual toggle, or a BMS control signal, allowing automated power management. The compact footprint and multiple mounting points make it easy to fit into existing electrical enclosures or tight spaces.

For higher power requirements, multiple units can be connected in parallel with no practical limit, providing a scalable solution that grows with your system.
