Meet the Victron Orion-TR 12/12-18A Isolated DC-DC Converter—a compact, reliable power module that delivers a clean, isolated 12 V output from a 12 V source. It’s ideal for automotive, marine, and off-grid systems that require ground-loop free power and easy remote control.
-
Isolated Output: Galvanic isolation of 200 VDC between input, output, and case to protect sensitive electronics and reduce ground-loop issues.
-
Remote On/Off: Control with a low-power signal via the remote terminal—perfect for engine run/stop signals or low-current control circuits.
-
Paralleling Capability: An unlimited number of units can be connected in parallel to increase output current as your system expands.
-
Protection & Reliability: Short-circuit and high-temperature protection with output current reducing at high ambient temperatures to protect the load.
-
Rugged Mounting: IP43 protection when screw terminals are oriented downward; quick, tool-free installation via screw terminals.
-
Input & Wiring: Input fuse (not replaceable) on 12 V and 24 V input models; maximum cable cross-section 16 mm² (AWG6).
-
Wide Input Range: 8–17 V input with undervoltage shut down at 7 V and restart at 7.5 V.
-
Precise, Adjustable Output: Nominal output 12.2 V; adjustable 10–15 V; output voltage tolerance ±0.2 V; noise 2 mV rms.
-
Performance: Continuous output current 18 A at nominal voltage and 40°C; 10-second max 25 A; continuous power 280 W at 25°C and 220 W at 40°C; efficiency 87%.
-
Low Idle Draw: No-load input current < 80 mA; current consumption < 200 µA when disabled via its remote port.
-
Physical & Installation: DC connection via screw terminals; max 16 mm²; weight 1.3 kg; dimensions 130 × 186 × 70 mm.
-
Not Battery Charging: Not intended for battery charging (for charging use an Orion-Tr Smart).
-
Applications: Designed for reliability in harsh environments, delivering isolated power for automotive, marine, and off-grid projects; protects sensitive electronics and simplifies remote switching.
With galvanic isolation, you shield sensitive electronics from vehicle or vessel power variations and ground loops, while the remote On/Off and parallel-capable design offer flexible, scalable control and power in compact spaces. The Orion-TR 12/12-18A provides precise regulation, robust protection, and a compact footprint suited for harsh environments—making it a dependable backbone for automotive, marine, and off-grid systems requiring clean, isolated 12 V power.
