Product information

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

Key specifications

Nominal input line voltage: 100 V
Compact housing dimensions: 105 × 105 × 65 mm
Multicolour enclosure for visual identification
Designed for line transformer ranges compatible with 30 W to 480 W systems
Available taps for 50 V, 70 V and 100 V line configurations
Selectable low-impedance side options intended for 2 Ω, 4 Ω and 8 Ω loads
Mounting compatibility with TR3000 installation plate and supplied accessories

How to use

Install the transformer on the TR3000 installation plate or suitable mounting surface using the supplied accessories. Connect the primary side to the 100 V distribution line following standard wiring practices for audio or monitoring systems and ensure polarity is observed. Route the secondary output to the measurement device, amplifier input or monitoring circuit while maintaining proper isolation and grounding per installation guidelines. Verify connections and perform a functional test at low levels before commissioning the system.

Usage recommendations

For safe and accurate operation, use the TR3120 within the specified 100 V line environment and select matching taps and low-impedance settings according to the connected load. Maintain appropriate clearance and secure mounting on the TR3000 plate; perform regular visual inspections and electrical checks as part of preventive maintenance.
