< - Product Description Low-frequency transformers are used to propagate signal voltage and signal power. They can also achieve impedance matching between circuits and have an isolation effect on DC. There is no difference in principle between high-frequency transformers and low-frequency transformers. However, due to the different frequencies of high-frequency and low-frequency transformers, the iron cores used in the transformers are different. Low-frequency transformers generally use silicon steel sheets with high magnetic permeability, while high-frequency transformers use high-frequency ferrite magnets. core.
The low-frequency transformer is designed and manufactured using high-quality silicon steel sheets with low power consumption. It has the advantages of small no-load loss, large output power, high efficiency, low temperature rise, low noise, stable and durable performance, etc. It is widely used in information and communication power supplies, lighting, air conditioners, audio power amplifiers, power supply instruments and equipment, various household appliances, etc.
