Victron Energy Orion-Tr 48/12-30A (360W) DC-DC Converter

The Victron Energy Orion-Tr 48/12-30A (360W) is a high-efficiency, non-isolated DC-DC step-down converter designed to convert a nominal 48V DC input to a stable 12V DC output. With a continuous output current of 30A and power of 360W, it is ideal for applications such as telecom, industrial, and automotive systems where reliable voltage conversion is required. The converter features remote on/off capability, screw terminal connections, and comprehensive protection against short circuit, over temperature, and input over/under voltage.

Advantages

High efficiency of over 92% minimizes power loss and heat generation. Compact and robust design with IP43 protection rating when installed vertically. Wide input voltage range (32-70V) ensures compatibility with various battery systems. Low standby current (<20mA) and excellent voltage regulation (<±0.2%) provide stable performance.

Suitable for

• Telecommunication equipment
• Industrial control systems
• Automotive and marine electronics
• Renewable energy systems (e.g., solar battery banks)
• LED lighting and audio systems
