600 : 600 Ohm EI Power Transformer 1:1 EI14 Audio Isolation Transformer

1.Product Description

EI14 Audio isolation transformers typically use an EI type core shape. The “EI” in “EI14” indicates that the core shape is a combination of E-type and I-type, and “14” generally refers to the size of the core. Its main parameters include:

--Voltage ratio: commonly 1:1, can make the input and output voltage is basically equal.

--AC impedance: 600:600 ohms, to ensure that the audio signal in the transmission process to achieve a good - good match.

--Inductance: Approximately 290mH (±20%), which helps to properly process the AC component of the audio signal.

--DC resistance: approximately 135 ohms or 140 ohms.

--Frequency Response: Generally in the range of 20Hz-20kHz, covering the audible audio range of the human ear.

2.Function

--Noise and interference elimination: EI14 Audio Isolation Transformer can eliminate the noise and interference generated by ground imbalance, common mode noise and ground loop, etc., making the audio signal purer.

--Impedance matching: EI14 Audio Isolation Transformer realizes the impedance matching between audio devices, ensures that the audio signal can be effectively transmitted from one device to another, improves the signal transmission efficiency, and reduces the signal reflection and distortion.

--Protecting equipment: Isolation transformer can isolate the equipment from possible high voltage or electrical faults, protect the audio equipment from damage and prolong the service life of the equipment.
