Isolated DC-DC converter Orion-Tr 24/12-9A (110W) DC-DC

The primary function of this converter is to convert a 24 V DC input into a 12 V DC output. It provides galvanic isolation between input and output, which is essential to prevent stray currents and electrical interference in marine or automotive systems.

This converter is designed for a nominal input voltage of 24 V DC, with an operating range of 16 to 35 V DC. The nominal output voltage is 12.2 V DC and is adjustable.

The Orion Tr 24/12-9A converter can provide a continuous output power of 110 W at an ambient temperature of 25 °C. This power is reduced to 85 W if the ambient temperature reaches 40 °C.

The DC output current of this converter is 9 A at an ambient temperature of 25 °C. It can also supply a maximum output current of 12.5 A for 10 seconds.

Galvanic isolation is an electrical separation between two circuits that prevents unwanted DC current from flowing while allowing energy or signals to be transferred. In the case of this converter, it is 200 V DC between the input, output, and housing, providing protection against ground loops, reducing electrical interference, and improving system safety.

Yes, the output voltage of this converter is adjustable. It can be set between 10 and 15 V DC using an integrated potentiometer. The default value is 12.2 V.

This converter displays an efficiency of 85%. High efficiency means less energy loss as heat and more efficient use of battery power.

Yes, Orion-Tr converter models with a 12 V or 24 V input, like this one, have an internal input fuse. This fuse is not user-replaceable.

The dimensions of the Orion Tr 24/12-9A converter are 100 x 113 x 47 mm (height x width x depth). Its weight is 0.42 kg.

This converter integrates multiple protections to ensure system safety and reliability:

Output short-circuit protection.Overload protection.High-temperature protection with automatic output current reduction in case of overheating.Input undervoltage protection with automatic disconnection and reconnection.

The on/off remote function is controlled by a dedicated socket. It allows you to operate the inverter using a low-power switch (switched current below 100 mA) or, for example, via the engine's on/off switch. This eliminates the need for a high-current switch on the input wiring.

Yes, an unlimited number of these converter units can be connected in parallel to increase the total output current. It is important to always set the output voltage of each unit before connecting them in parallel.

To achieve IP43 protection, which guards against dust and water spray, the unit must be installed with the terminal blocks facing downward.

The converter uses screw terminals for DC connections. No special tools are required for cable installation.

The terminals on this converter accept a maximum cable cross-section of 6 mm² (AWG10).

This converter can operate within a temperature range from -20 °C to +55 °C. Above 40 °C, the output current is reduced by 3 % per degree Celsius. The maximum permitted humidity is 95 % without condensation.

Although the output voltage is adjustable, this converter is not primarily designed for battery charging. For optimal charging and advanced features, it is recommended to use a converter from the Victron Energy Orion-Tr Smart range, specifically designed for this purpose.

Yes, thanks to its 200 V DC galvanic isolation and low output noise (2 mV rms), this converter is suitable for powering sensitive electronic equipment by reducing interference and ensuring stable power supply.

This converter accepts an input voltage range of 16 to 35 V DC. It also features a low-voltage disconnect threshold at 14 V and reconnect threshold at 15 V to protect the input source.
