Frequently asked question (FAQ)
- Question: What is the function of a noise filter?
-
Answer:
The main functions of a noise filter are as follows:
1. Prevent external electromagnetic noise from interfering with the operation of the control circuit of the power supply equipment itself;
2. Prevent external electromagnetic noise from interfering with the operation of the power supply load;
3. Suppress EMI generated by the power supply device itself;
4. Suppress EMI generated by other devices and propagated through the power supply. - Question: What are the main applications of noise filters?
- Answer: Noise filters are widely used in automated production lines and precision equipment, hospital systems, automotive manufacturing, semiconductor industries, etc.
