EI power supply transformers are made of good quality silicon sheet, which loses little power. This kind of transformers features low no-load loss, high output power, efficiency, low temperature, and low noise. They are widely used in air-conditioners, VCD, Hi-fi Audios, power amplifiers, power supply devices, metering devices and others.
