Application Scope & Usage

This three phase EMI filter is used to eliminate electromagnetic interference on three phase AC power supply lines. It stabilizes power input and protects sensitive electronic components from power noise. It is widely used in high power industrial automation equipment, large power control systems, industrial drives and other heavy duty machines that require strict EMC performance. It prevents abnormal operation caused by power interference and guarantees continuous and stable running of industrial equipment.

Five General FAQ

1. Q What is the main function of an EMI power filter A An EMI power filter is designed to suppress electromagnetic interference on AC power lines. It attenuates common mode and differential mode noise purifies input power quality protects sensitive electronic circuits and helps finished products meet EMC test requirements.
2. Q How to choose the correct current rating for a power filter A The rated current of the filter should be higher than the maximum continuous working current of your equipment. It is recommended to reserve a certain current margin to avoid overload which will affect filtering performance and service life.
3. Q What is leakage current of power filter and does it affect my equipment A Leakage current refers to the tiny current flowing from the power line to the ground through the filter’s Y capacitor. It is an inherent parameter of EMC filters. You need to select a filter with leakage current within the safe range according to your product type especially for medical and touchable devices.
4. Q What is the difference between single phase and three phase EMI power filters A Single phase filters are used for 2 wire or 3 wire single phase AC power supply systems commonly seen in consumer electronics and small industrial devices. Three phase filters are applied in three phase AC power circuits for high power heavy duty equipment such as motors and large industrial controllers.
5. Q What should I pay attention to during filter installation A Keep the input and output wiring separated to prevent noise re coupling. Make solid and short ground connection. Install the filter as close as possible to the power inlet of the device which can maximize the noise suppression effect.
