Low Frequency Transformer With Holder

Low Frequency Transformer With Holder

Low Frequency transformers are used in markets as industrial, vending or lighting where energy conversion is still needed. They are an easier solution than high frequency transformers, but as effective as the others. At Sitong Electronic we have different size of those transformers depending on the power range where is necessary to work.The low-frequency transformer is used to transmit signal voltage and power, and can also realize impedance matching between circuits. There is no difference in principle between a high-frequency transformer and a low-frequency transformer. But because the high and low frequencies are different, the transformer USES different cores.Low-frequency transformers generally use high permeability silicon steel sheet, high-frequency transformers use high-frequency ferrite core.

The low frequency transformers are used to transmit signal voltage and power, it could also match impendance in different circuits.
