High Efficiency EI14 Vertical Low Frequency Transformer Silicon Steel Core Mini PCB Vertical Pin Type Transformer

High Efficiency EI14 Vertical Low Frequency Transformer Silicon Steel Core Mini PCB Vertical Pin Type Transformer

1.Product Function Overview

EI14 vertical transformer is a low-frequency audio isolation transformer based on silicon steel core. Its core functions include audio impedance matching, ground loop noise elimination, electrical isolation between primary and secondary circuits, and low-frequency voltage conversion. It stabilizes audio signal transmission, filters clutter interference, and provides safe isolated power supply for small voice communication equipment. 

2. Application Fields

• Audio & communication devices: landline telephones, building intercoms, doorbell voice modules, mini Hi-Fi speakers, audio mixer signal isolation boards
• Small household appliances: humidifiers, massage devices, mini fans, aromatherapy machine control power boards
• Security equipment: access control voice intercom modules, simple alarm detectors
• Small industrial instruments: low-frequency signal isolation panels, portable medical mini equipment
