Victron Orion-Tr 48V to 24V - 280W 12A Isolated DC-DC Converter (SKU Part Number ORI482428110)

Overview of the Victron Orion-Tr DC-DC Converter

The remote on/off 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 by for example the engine run/stop switch (see manual). All models are short circuit proof and can be paralleled to increase output current. An unlimited number of units can be connected in parallel.
