The Victron Orion-TR 12/48-8A (380W) Isolated DC-DC Converter delivers a robust, isolated 48V output from 12V or 24V systems. Built for demanding environments, this module provides clean power conversion with galvanic isolation and smart protections, ideal for harsh automotive, marine, RV, and industrial applications.
-
Remote On/Off terminal: eliminates the need for a high-current input switch. Operate the unit with a low-power switch or engine run/stop control for convenient, safe startup and shutdown.
-
Paralleling capability: no practical limit on the number of units that can be connected in parallel to increase output current.
-
Protection you can rely on: short-circuit proof with high-temperature derating, IP43 protection when screw terminals are oriented downward, and a built-in input fuse (on 12V/24V models only).
-
High-quality isolation: 200 VDC galvanic isolation between input, output, and case for safer system integration.
-
Efficiency and performance: up to 89% efficiency with continuous output of 430 W at 25°C (380 W at 40°C) and a maximum output current of 25 A short-circuit, 8 A continuous at nominal voltage.
-
Low-noise, stable output: nominal 48.2 V output with an adjustable range from 40 to 60 V and tight voltage tolerance of ±0.2 V; output noise of 2 mV rms.
-
Not for battery charging: not intended for charging batteries (consider an Orion-Tr Smart for battery charging).
