EMC Filter for the LM AC/DC Enclosed SMPS - FC-LxxWx Series

Introduction

EMC interference caused by application environmental is common during power supply design. MORNSUN announced the introduction of its new EMC filter FC-LxxWx series for the AC/DC enclosed switching power supplies.

Advantages

1. High Immunity to CM & DM Interference

Based on the first-order filtering scheme, the EMC filter FC-LxxWx series has a high immunity to CM & DM interference, which can effectively ensure the stability and reliability of the whole system.

• FC-L03Wx’s immunity to CM interference: 50dB@20MHz

• FC-L03Wx’s immunity to DM interference: 75dB@10MHz

• FC-L06Wx’s immunity to CM interference: 55dB@20MHz

• FC-L06Wx’s immunity to DM interference: 75dB@10MHz

2. High Immunity to surge voltage

There is an excellent impact on the rear equipment because of the surge caused by the fluctuation of power grid. Besides, the improper protection of the back equipment may also cause faults or rebooting. FC-LxxWx products applied to the power supply input have high immunity to surge voltage, such as the surge of DM up to 4kV and surge of CM up to 6kV. (Conventional filters can support 2kV/4kV).

3. Good EMI Immunity performance

• CE CISPR32/EN55032    CLASS B

• RE CISPR32/EN55032    CLASS B

4. Multiple packages for a wide range of applications

• Standard series are wiring package: 85*39*28.9mm

• Series with suffix “A2S” are chassis mounting: 85*39*29.9mm

• Series with suffix “A4S”are DIN rail mounting: 89*39*36.4mm

5. Compliance with Industry Safety

FC-LxxWx series features high reliability with CE markings (IEC60939/62368). When used with MORNSUN Enclosed switching power supplies LM series, the EMI performance of the whole system can be improved.

Applications

FC-LxxWx series can be used with MORNSUN Enclosed switching power supplies LM series (LM35, LM100, LM200, LM350, etc.) for the applications of High-speed railway power, welding machine, inverter, photovoltaic inverter, motor inverter, UPS power supply, charging pile, motor control, etc.
