## Long description

Audac TR3120 is a current transformer designed for 100 V nominal input systems. The compact unit measures 105×105×65 mm and features a multicolour housing that supports integration into professional audio and electrical environments. It converts primary current into a measurable secondary signal while providing isolation and level matching for 100 V distribution lines, enabling safe sensing and interfacing for monitoring or audio distribution applications.
Advantages
The TR3120 provides galvanic isolation between the high-voltage 100 V line and downstream measurement or amplification equipment, reducing the risk of interference and ground loops. Its compact dimensions and multicolour housing simplify installation and visual identification in systems with multiple transformers. The design supports reliable current conversion for both measurement and audio line distribution, and the product is compatible with the TR3000 installation plate and related mounting accessories for quick and secure mounting.
Suitable for
Level matching and current sensing in 100 V audio distribution systems
Electrical monitoring of line currents in commercial audio installations
Integration into distributed public address or paging systems
Applications requiring galvanic isolation between source and measurement equipment
