Victron Orion-Tr 24/48-8,5 (400W) Isolated DC-DC Converter
Pickup available at Mercury Yacht Harbour

Description
The Victron Orion-Tr 24/48-8,5 is an isolated DC-DC converter rated at 400W continuous, converting a 16-35 V input into a nominal 48.2 V output. The output voltage is adjustable across 40-60 V, and galvanic isolation of 200V DC is provided between the input, output and case, which makes it suitable for systems where the input and output grounds must be kept separate.
All models are short circuit proof and protected against over temperature, with the output current reducing progressively at high ambient temperatures. A remote on/off terminal removes the need for a high current switch in the input wiring and can be operated by a low power switch or, for example, an engine run/stop signal. The unit is rated to IP43 when installed with the screw terminals facing downwards, and an unlimited number of units can be connected in parallel to increase the available output current.
The output voltage is adjustable and the Orion-Tr converter is not intended for battery charging. Where a regulated charge profile is required, use an Orion-Tr Smart DC-DC charger instead.
