FAQ
Q: What is the function of an AC Line EMI Filter?
A: An AC Line EMI Filter suppresses conducted electromagnetic interference on power lines. It prevents noise generated by electronic equipment from flowing back into the power grid and also blocks external disturbances from affecting equipment operation. It is a key component for achieving EMC compliance.
Q: How do I choose between single-phase and three-phase EMI filters?
A: Select the filter according to the power supply system.
Single-phase EMI filters are commonly used for household appliances, office equipment, and single-phase motors.
Three-phase EMI filters are designed for industrial equipment, frequency converters, motor drives, and high-power UPS systems.
Q: How should I select the rated current?
A: The filter's rated current should be higher than the maximum operating current of the equipment. A 20–30% safety margin is recommended for reliable operation.
For example:PE2100 series supports up to 100 A
PE3300/PE3400 series supports up to 1200 A
Q: Why is leakage current important?
A: Leakage current is the small current flowing from the filter to ground during normal operation. It is especially important in medical applications where strict safety limits apply (typically <0.5 mA). Low-leakage-current models, such as medical-grade versions, help meet healthcare equipment safety requirements.
