Orion-tr DC-DC converter 24V/48V-8.5A (400W) isolated

This converter is designed to transform a 24V DC input into a 48V DC output. It is ideal for powering equipment requiring a 48V supply from a 24V source, while providing galvanic isolation to protect sensitive systems.

The Orion-Tr DC-DC converter 24V/48V-8.5A can deliver a continuous power output of 400W at an ambient temperature of 40°C.

This converter accepts a nominal input voltage of 24V DC, with an operating range from 16V to 35V DC. The nominal output voltage is 48.2V DC, and it is adjustable.

Yes, the output voltage is adjustable via a potentiometer. It can be set from approximately -15% to +25% of the nominal 48.2V value, corresponding to a range of 40V to 60V DC.

The 200V DC galvanic isolation between the input, output, and housing means there is no direct current path between these circuits. This isolation is essential to prevent ground loops, reduce interference, and protect sensitive electronic equipment in complex installations, particularly in marine environments.

No, this converter is not designed for battery charging. For battery charging, it is recommended to use an Orion-Tr Smart model.

This Orion-Tr DC-DC 24V/48V-8.5A (400W) converter has an efficiency of 89%.

The converter dimensions are 130 x 186 x 70 mm (height x width x depth). Its weight is 1.7 kg.

The converter can operate within a temperature range from -20°C to +55°C. Above 40°C, the output current is automatically reduced (3% derating per °C).

The converter has IP43 protection, provided the screw terminals are oriented downward during installation. Maximum humidity without condensation is 95%.

The converter has a remote on/off terminal. You can replace the jumper wire on the green connector with a low-power switch (switched current less than 100 mA), or remove the jumper wire and connect the right terminal of the green connector to the positive pole of the battery with a switch (for example, an engine start/stop switch).

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

Yes, the converter is fully protected against short circuits and overloads. It also includes high-temperature protection that automatically reduces the output current if necessary.

For DC connections, it is recommended to use cables with a maximum cross-section of 16 mm² (AWG6). Connections are made via screw terminals, requiring no special tools.

Yes, models with a 24V input voltage (like this one) have an internal input fuse. This fuse is not replaceable.

To adjust the output voltage, use the potentiometer located either to the left or right of the terminal connections, depending on the model. Turn counterclockwise to decrease the voltage and clockwise to increase it.

Yes, this converter is designed for demanding environments, including marine applications. Its galvanic isolation and IP43 protection (with terminals facing downward) make it suitable for these conditions.

This converter is compatible with any equipment requiring a 48V DC power supply and a maximum current of 8.5A (400W), powered from a 24V DC source. Its galvanic isolation makes it particularly suitable for systems where protection of sensitive equipment is critical.

The converter produces a 2 mV rms output noise. This value is specified to ensure stable and clean power supply to connected equipment.

Idle current draw (when the inverter outputs voltage but no load is applied) is less than 120 mA for this 24/48-8.5A model.
