The Victron Orion-Tr 24/12-20 is a non-isolated DC-DC converter that steps a 24V DC supply down to a stable 12V output, delivering up to 20A continuous at a 240W rating. It suits vehicles, boats and off-grid systems where a 24V house or starter battery needs to power 12V equipment reliably. This retail version is boxed for direct sale and installation by trade professionals or competent DIY installers.

Key features of this victron dc dc converter

• Output, regulated 12V DC at up to 20A continuous current
• Power rating, 240W continuous, with short-circuit and overload protection built in
• Converter type, non-isolated, so input and output share a common negative
• Housing, compact aluminium casing suited to vehicle and marine environments
• Input tolerance, wide input voltage range copes with fluctuations from alternators and battery banks without dropping output
• Standby draw, low power consumption when the connected load is switched off

Product overview

Because it is non-isolated, the negative terminals of input and output are electrically common. This keeps the unit compact and efficient, but it is not suitable where galvanic isolation is required, such as some battery charging setups or systems with earth-referenced electronics. Check the vehicle or vessel's electrical architecture before specifying this unit over an isolated equivalent.

At 240W and 20A, it is sized for moderate 12V loads rather than high-draw equipment: accessory circuits, communications gear and smaller 12V appliances running from a 24V supply.

Applications

• Powering 12V accessories from a 24V commercial vehicle or truck electrical system
• Supplying 12V equipment on boats with a 24V house battery bank
• Running 12V communications, audio or navigation equipment from a 24V supply
• Off-grid and mobile installations needing stable 12V power from a 24V source

What's in the box

• 1 x Orion-Tr 24/12-20 (240W) DC-DC converter
• Retail packaging

Installation notes

Confirm a non-isolated converter suits the electrical system before fitting, since input and output negatives are common. Use correctly rated cable and fusing on both sides. Installation should be carried out by someone familiar with 12V and 24V DC systems, particularly in vehicles and vessels where wiring standards and earthing arrangements vary.
