In many power supply designs and applications, the main power circuits often have high EMC interference. To increase their anti-interference capability, MORNSUN has released the FC-LxxWx series of EMC filters as a supplement to meet the design requirement of AC/DC enclosed power supplies, especially for LM/LMF series products.
Any fluctuation in the power supply circuits will cause a surge, which could affect the back-end devices. In conventional circuits, the surge is differential mode (DM) ±2 kV/common mode (CM) ±4 kV. However, in complex environments, surge interference may be far higher. The FC-LxxWx series, a filter module applied at the input of the power supplies, has a strong immunity to surge voltages of DM up to 4 kV and CM up to 6 kV.
These EMC filters, based on the second-order filtering scheme, mitigate performance to CM/DM interference up to 60 dB, which can effectively suppress interference, and improve the conduction level of the LM series power supply products.
