Victron Orion-Tr 24/48-8.5A Isolated DC-DC Converter: Clean, Stable Power for Sensitive Electronics

Galvanic Isolation for Superior Noise Rejection and System Protection

The Victron Orion-Tr 24/48-8.5A 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 20-35V, 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 40-60V, 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 (20-35V) with under-voltage shutdown and restart for battery protection
  • Adjustable output voltage (40-60V) 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 12V or 24V to sensitive appliances like compressor fridges, LED lighting, and entertainment systems, regardless of battery voltage sag.
  • Off-grid solar systems: Step voltage up or down 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.

Power Your Critical Systems with Confidence

When clean, stable DC power is essential, trust the Victron Orion-Tr 24/48-8.5A to deliver. Whether you're outfitting a bluewater yacht, a remote off-grid cabin, or a mobile command vehicle, this isolated converter provides the reliability and performance that professionals demand. Add it to your power system today and eliminate electrical noise for good.

There is a war... for your Mind!
Format: Kindle
"There is a war... for your Mind!" That's the slogan of InfoWars, the incendiary conspiracy news network and nutritional supplement marketing firm. And while Alex Jones is wrong about almost everything, he's right about that. In LikeWar Singer and Brooking ably synthesize a sophisticated picture of information warfare in 2018, drawing from sources as diverse as Taylor Swift, Donald Trump, and ISIS, to argue that the internet has lead to a blurring of lines between consumer, citizen, journalist, activist, and warrior which threatens the foundations of liberal democracy. The tech companies which built these platforms and profited from them must grapple with the politics of their technologies, before we all reap the whirlwind. Computer networks and smart phones connect billions of people, allowing ideas to flow faster than ever before in history. Sometimes, the results can be impressive. The Chiapas Zapatista movement in 1994 was a dial-up and fax version of a network insurgency that managed to bring enough international opprobrium on Mexico that the government blinked, and reached some kind of political accord (Chiapas is complicated). More recently, Eliot Higgins and a team of open source analysts at Bellingcat managed to track down the exact BUK missile system and Russian soldiers responsible for shooting down MH 17 in 2014. But there are a lot of dark sides. When people connect, the emotion that spreads most rapidly is anger. Lies spread five times faster than truth. Musicians can use social networks to directly connect with their fans, and ISIS uses it to connect with alienated Muslim youths worldwide. Social networks sort diverse citizens into filter bubbles of people who think alike. Eliot Higgin's careful open source intelligence has a paranoid fun-house mirror version in the QAnon conspiracy, where Qultist decoders find hidden messages from an alleged 'senior white house source'. And then there is the matter of information war, an area that even now, after years of offensive cyber operations, liberal democracies still don't understand. Hostile propaganda slips into Western news networks and major platforms like Twitter, Facebook, and Instagram are infested with bots. LikeWar can even take a personal toll. Over the course of writing this book, General Michael Flynn went from forward looking full-spectrum commander to head Trumpist conspiracy cheerleader to indicted and plead out felon. Flynn's fall is complex, but it can't be separated from the internet. If the trolls got him, what chance does your idiot cousin stand? The counters, 'citizen truth teams' and senior emissaries to groups vulnerable to recruitment, seem like thin reeds against the coming maelstrom of noise. LikeWar starts with Clausewitz's dictum that war is a continuation of politics by other means, and there are clear links between cyberspace and physical space. Intensity of hashtags impacted the subsequent intensity of Israeli airstrikes during attacks on the Gaza strip. ISIS used propaganda to create an aura of invincibility that outflanked the defenders of Mosul, while Russia denied that its 'little green men' were even in Ukraine. But the difference is that cyberspace is constructed space rather than natural space. The networks are built, maintained, and owned by real corporations and real people. The internet grew from an anarchic specialized scientific network to a major engine of commerce and communicate with little deliberate government oversight. Section 230 absolved American companies of responsibility for policing content, with major carve outs for copyrighted IP and pornography. Yet as concerns over cyberbullying and counter-terrorism rose, major networks adopted digital constitutions that were permissive towards speech and censorious towards erotica. Policing content is and was possible, but always took a back seat to growth and engagement, the guide stars of Silicon Valley. The future is if anything, darker. Advances in machine learning and AI allow ever more realistic bots, computer generated DeepFakes where a politician can be programmed to say anything, and personalized targeting of people with exactly the propaganda they'll believe. There are defensive counters, but if I might draw military analogies, what we saw in 2016 was armored warfare circa 1918: clearly the future, but not yet a mature system. Given the pace of technology, we only have a few years before digital blitzkrieg. I'm extremely online, and I've been following this space for years. I've presented at multiple conferences on this topic, including Governance of Emerging Technologies and Association of Internet Researchers. LikeWar is the book I wish I'd written. Cognizant, forward looking, and deeply researched, it is vital reading for anyone interested in technology or politics. My only reservation is that I wish the sources were better linked in the text, instead of being buried in static endnotes. Maybe the next edition will push an update.

Making Sense of the Tactics Deployed in the Social Media War
Format: Hardcover
Singer and Brooking’s book, pulls together in one place the various threads of information about cyberthreats from the last few years, weaving them into a coherent, memorable, and understandable(!) whole. All these authors provide exhaustive lists of sources. It’s incumbent on responsible people to understand the tactics of information warfare, because, “[recent Senate hearings] showed that our leaders had little grasp on the greatest existential threat to American democracy,” said Leigh Giangreco in the Washington Post. These ill-intentioned manipulators understand the human brain is hard-wired for certain reactions: to believe in conspiracy theories (“Obama isn’t an American”); to be gratified when we receive approval (“likes”!); to be drawn to views we agree with (“confirmation bias”). If we feel compelled to weigh in on some bit of propaganda or false information, social media algorithms see this attention and elevate the issue—“trending!”—so that our complaints only add to the virality of disinformation and lies. “Just as the internet has reshaped war, war is now radically reshaping the internet,” the authors say. Contrary to the optimism of the Silicon Valley entrepreneurs who saw social media as a positive, democratizing force, this new technology is being used to destructive effect at many levels of society. At a local scale, for example, it bolsters gang violence in Chicago; at a national scale, it contributed to the election of fringe politicians; at a regional scale, it facilitated the emergence of ISIS; and at an international scale, it undergirds the reemergence of repressive political movements in many countries. How to be a responsible citizen in this chaos? Like it or not, “we’re all part of this war,” the authors say, “and which side succeeds depends in large part on how much the rest of us learn to recognize this new warfare for what it is” and how ready we are for what comes next.
