Victron Orion-TR 48/24-16A Isolated DC-DC Converter by Victron Energy

Orion-TR 48/24-16A (380W) Isolated DC-DC Converter

Isolated Model - separate in and out (-) leads

Remote On/Off Terminal

The remote on/off terminal 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 for example the engine run/stop switch.

All Models Are Short Circuit Proof and Can Be Paralleled to Increase Output Current

An unlimited number of units can be connected in parallel.

High Temperature Protected

The output current will reduce at high ambient temperatures.

IP43 Protection

When installed with the screw terminals oriented downward.

Screw Terminals

No special tools are needed for installation.
