Tridonic DC-String Bridge – Signal Converter for 48V LED Driver Systems

The Tridonic DC-String Bridge enables seamless signal conversion from analog 0–10V or digital DALI/DALI-2 to PLC (Power Line Communication), making it a key interface component for Tridonic 48V DC-String LED drivers and LMI boards. It’s designed for dimmable lighting control in commercial and architectural installations using Tridonic systems.

Bridge DALI / 0–10V to PLC – Tridonic Control Solution

This signal bridge allows integration of DC-String LED drivers into 0–10V or DALI control systems. It supports both group dimming via standard 0–10V dimmers and individual dimming with DALI, offering versatile control options through a compact, plug-and-play device.

⚠️ Note: The Tridonic DC-String Bridge is only compatible with Tridonic 48V DC LED drivers in combination with LMI boards. Compatibility with third-party drivers is not guaranteed.
