The Victron Orion-TR 12/48-8A (380W) Isolated DC-DC Converter delivers a robust, isolated 48V output from 12V or 24V systems, ideal for automotive, marine, RV, and industrial installations where reliable power in tight spaces matters.
-
Isolated 48V output: 48.2 V nominal output with galvanic isolation (200 VDC) between input, output, and case for safer system integration; adjustable 40–60 V with tight tolerance and low output noise.
-
Input compatibility: Designed to operate from 12V or 24V systems, input range 10–17 V; under-voltage shut down at 7 V and restart at 7.5 V.
-
Efficiency & power: Up to 89% efficiency; continuous output 8 A at nominal voltage, 430 W at 25°C (380 W at 40°C); peak 15 A for 10 seconds; short-circuit current up to 25 A.
-
Remote On/Off: Remote control terminal eliminates the need for a high-current input switch; enables startup/shutdown from a low-power control or engine/run-stop signal.
-
Paralleling capability: No practical limit on the number of units that can be connected in parallel to increase output current.
-
Protection & safety: Short-circuit proof with high-temperature derating; IP43 protection when screw terminals are oriented downward; built-in input fuse on 12V/24V models.
-
Output quality & regulation: Nominal output 48.2 V with 2 mV rms noise; output voltage adjustable from 40–60 V and tolerance of ±0.2 V.
-
Durability & specs: Operating range -20 to +55°C with 3% derating per °C above 40°C; humidity up to 95% non-condensing; weight 1.8 kg; dimensions 130 x 186 x 80 mm; uses screw terminals supporting up to 16 mm² (AWG 6) cables.
-
Not for battery charging: Not intended for charging batteries (for battery charging, consider the Orion-Tr Smart).
By converting 12/24 V input to a stable 48 V rail, the Orion-TR simplifies wiring, reduces ground-loop risks, and protects sensitive electronics with galvanic isolation. Remote On/Off provides convenient control, while its parallel-ready design allows scalable power for expanding systems. With robust protections, wide operating temperature, and a compact form factor, it’s a dependable choice for harsh automotive, marine, RV, and industrial installations. If you need battery charging capabilities, consider the dedicated Orion-Tr Smart variant.
