The Victron Orion-TR 24/12-20A Isolated DC-DC Converter provides a clean, regulated 12V output from a 24V input with galvanic isolation, delivering dependable power in demanding environments. It's designed for marine electrical systems, recreational vehicles, solar-powered setups, and off-grid installations that need a reliable 12V supply from a 24V source.
-
Isolated DC-DC conversion: 24 V input to a stable 12 V output with full galvanic isolation (200 VDC between input, output, and case) for system protection and safety.
-
Remote On/Off control: External control enables convenient power management without high-current wiring.
-
Paralleling capability: Unlimited units can be connected in parallel to increase output current as your load grows.
-
Rugged protection: High-temperature protection reduces output when ambient temperature rises to keep the unit safe and reliable; IP43 protection when terminals are oriented downward.
-
Durable construction: Screw terminals for easy installation without special tools; input fuse (non-replaceable on 12 V/24 V models) adds an extra layer of protection.
-
Wide input range: 16–35 V input with undervoltage shutdown at 14 V and restart at 15 V for robust automotive/industrial use.
-
Precise output: Nominal 12.2 V output with an adjustable range of 10–15 V and tight tolerance ±0.2 V; low output noise at 2 mV rms.
-
Efficiency and thermal performance: Up to 88% efficiency to minimize heat and maximize battery life; operating temperature -20 to +55 °C with a 3% derating per °C above 40 °C.
-
Current and safety specifications: Continuous output current 20 A (300 W at 25 °C; 240 W at 40 °C); peak 25 A for 10 seconds; short-circuit current 50 A; isolation 200 VDC (input-output-case).
-
Not for charging applications: Not intended for battery charging; for charging setups, consider the Orion-Tr Smart.
-
Physical and electrical connectivity: Weight 1.3 kg; dimensions 130 x 186 x 70 mm; screw terminals with max cable cross-section 16 mm² (AWG 6); input fuse included on some models.
-
Certifications and safety: Safety EN 60950; Immunity EN 61000-6-2, EN 61000-6-1, EN 55014-2.
With galvanic isolation and scalable control features, this converter protects both battery systems and sensitive electronics while delivering stable, low-noise 12V power across marine, RV, solar, and off-grid applications. The rugged, easy-to-install design and broad input range support reliable operation in harsh environments, helping electronics, lighting, and accessories perform consistently from a 24V source.
