Victron Orion-Tr 24/12-20 DC-DC Converter – 24V to 12V 20A Isolated Converter

The Victron Orion-Tr 24/12-20 isolated DC-DC converter converts 24V power to 12V, so you can power 12V appliances on a 24V electrical system. This 20A model outputs up to 20A.

This model is not designed to be used as a battery charger. This model has an adjustable output voltage range of 10V-15V.

You can connect an unlimited number of this model in parallel.

DC-DC converter

A DC-DC converter converts the input voltage of 24V to the output voltage of 12V.


Isolated DC-DC converters are suitable for systems grounded to a negative bus bar.

Screw terminal connection points

This DC-DC converter has Tr screw terminal connection points. So, you will need to strip your input and output wires of a short length of insulation to fix them to the screwed terminal.

DC-DC converter – use cases

In a system with multiple voltages, a DC-DC converter is needed to convert the main system voltage to the desired voltage. E.g. in a system with 12V leisure batteries, a DC-DC converter converts 12V to 24V to power any 24V appliances.

You can use the Orion DC-DC converters for both lead-acid and lithium batteries. We stock models up to 400W.

Suitable for high temperatures up to 55°C with a full rated output up to 40°C.
