EMC Filter for Railway Power Supplies – (CE Marking) FC-CxxD Series

Nov 22, 2022 | Product Posts

Introduction

Mornsun’s Railway Power Supplies have high EMC performance and can be widely used in onboard switching, train controlling, and other onboard devices. However, for special applications which have higher EMC performance requirements, filters would be necessary for anti-interference design purposes, thus Mornsun launched the FC-CxxD products, a series of EMC filters as a supplement to meet the design requirement specifically.

Advantages

Strong Immunity to CM & DM Interference

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

Strong Immunity to surge voltage

The surge caused by the fluctuation of power circuits has a great impact on the rear equipment and improper protection of the rear equipment may cause faults. The FC-CxxD series, a filter module applied in the input of the power supplies, has a strong immunity to surge voltage in conventional circuits, such as the surge of DM up to 2kV and surge of CM up to 4kV.

Compliance with Industry Safety

FC-CxxD series features high reliability with CE markings (EN62368) and meets the railway industry standards (EN50155、EN50121-3-2). Its designs are combined with the main products in the market and can be adapted with MORNSUN railway power supplies UWTH1DxxQB-xxW (H/F) R3 series, meeting the CISPR32/EN55032 CLASS B standard.

Features

  • Ultra-Wide input voltage range: 14-160VAC
  • High efficiency up to 98%
  • Operating temperature range: -40℃ to +105℃
  • Insertion loss >55dB@7MHz
