The CE mark stands for "Conformité Européenne," indicating European Conformity. It is a self-declaration from manufacturers that their products meet safety, performance, environmental, and electromagnetic compatibility (EMC) standards required by the EU. This applies to all electrical products, with OEM equipment needing to adhere to three major directives: EMC Directive 2014/30EU, Machinery Directive 2006/42/EC, and Low Voltage Directive 2014/34/EU
This whitepaper from Enerdoor introduces their EMI-RFI Parallel Filter series, a hybrid filtering solution with over 25 years of use across industrial applications. The document identifies a key regulatory gap — a "black hole" between 4 kHz and 150 kHz that is not covered by any international standard, including IEEE519, IEC 61000-3-12, or FCC/IEC frameworks. VFDs and servo drives, which are common sources of high-frequency noise, produce emissions in precisely this unregulated range, causing malfunctions in sensitive equipment such as PCs, UPS systems, sensors, and security devices. Enerdoor's parallel filter addresses this by operating across 10 kHz to 6 MHz, functioning as a parallel rather than series device, which means it works at any current level and across voltages from 0 to 750 Vac. Two models are offered: the FIN230SP.001.M, a general-purpose filter effective from 70 kHz to 6 MHz suited for most OEM applications, and the FIN730.001.M, a more specialized design for regenerated systems covering 10 kHz to 4 MHz. The filters are available in compact din-rail or panel mount packages and are positioned for OEMs using drives in unregulated markets, system integrators managing field noise risks, and end users in environments ranging from hospitals to large industrial plants where RF interference can compromise sensitive equipment.
Enerdoor's ground noise reduction filter is designed to minimize radio frequency interference inside machines caused by devices like VFDs and servo drives. The filter works as a buffer between the clean ground point and noisy points, effectively reducing common mode noise in high-frequency bands.
