Victron Energy Orion-TR 24/24-17A Isolated DC-DC Converter – 400W, 24 VDC to 24 VDC

Orion-TR 24/24-17A (400W) Isolated DC-DC Converter

Isolated Model - separate in and out (-) leads

Remote On/Off Terminal

The remote on/off terminal eliminates the need for a high current switch in the input wiring. The remote on/off can be operated with a low power switch or for example the engine run/stop switch.

All Models Are Short Circuit Proof and Can Be Paralleled to Increase Output Current

An unlimited number of units can be connected in parallel.

High Temperature Protected

The output current will reduce at high ambient temperatures.

The Victron Energy Orion-TR 24/24-17A is an advanced isolated DC-DC converter designed for reliable power conversion in demanding environments. With a continuous output power of 480 watts at 40°C and an output current of up to 17 amps, this unit ensures consistent power delivery for various applications. The isolated design features separate input and output grounds, reducing electrical noise and providing safer operation in complex systems. Its galvanic isolation of 200 VDC enhances safety and system stability, making it suitable for industrial, automotive, and marine use.
Equipped with a remote on/off terminal, the Orion-TR allows remote control of the power state, eliminating the need for high-current switches in input wiring. This feature simplifies installation and reduces wiring complexity, especially when integrated with engine run/stop systems or low-power switching devices. The unit is protected against short circuits, with a maximum short circuit output current of 40 amps, and can be paralleled with an unlimited number of units to increase overall current capacity, providing flexibility for expanding systems.
The converter is built with fanless cooling and high temperature protection, which reduces output current as ambient temperatures rise, ensuring long-term reliability. Its IP43 rated enclosure, when installed with screw terminals downward, offers protection against dust and limited water exposure. Easy-to-use screw terminals facilitate installation without specialized tools, and the input fuse on 12V and 24V models provides additional protection, although it is not replaceable. The adjustable output voltage, ranging from 20 to 30 volts, allows fine-tuning to meet specific system requirements, though it is not intended for battery charging applications.
This converter operates efficiently at 89%, with minimal no-load current draw of less than 80 mA. It supports a wide input voltage range of 20 to 35 volts and is suitable for environments with temperatures from -20°C to +55°C, with derating above 40°C. Its compact dimensions and lightweight construction make it suitable for installation in a variety of settings, while compliance with EN 60950 safety standards ensures safe operation. The Orion-TR is an ideal choice when high-power, reliable DC-DC conversion with galvanic isolation and remote control features are required for your system.
