UI39 Audio Transformer 150/600 40Vrms High Quality M6 Silicon Steel Sheet for Audio Isolation
1.Product Description
This is a UI39 series audio isolation transformer made of high-quality M6 silicon steel sheets. Its core function is to perform high fidelity signal conversion and matching between 150 Ω and 600 Ω impedance systems. This transformer has a high operating voltage capacity of 40Vrms and can reliably process professional level line level signals. Its all steel shielded shell can effectively suppress electromagnetic interference and ensure pure audio transmission. Suitable for broadcasting equipment, professional audio systems, and audio interface scenarios that require electrical isolation, it can completely eliminate grounding circuit noise, achieve stable and low distortion signal isolation and impedance conversion.
Summary of Core Features
1. Professional impedance matching: The core function is to perform impedance conversion between 150 Ω and 600 Ω systems, achieving maximum signal power transmission and reducing reflection.
2. High voltage processing capability: A rated voltage of 40Vrms means it can easily handle line levels of+24dBu or even higher in professional audio equipment, with sufficient dynamic margin and less susceptibility to magnetic saturation.
3. High quality magnetic core: M6 silicon steel sheet ensures excellent audio performance, including wide frequency response, low distortion, and low loss.
4. Good shielding: The steel casing effectively resists electromagnetic interference and is suitable for complex electronic equipment environments.
5. Sturdy structure, suitable for industrial installation: The installation hole position of M6 indicates that it is designed for bolt fixing and is suitable for occasions that require reliable mechanical connections.
