What EMI mains filters are available from Akyga®?
We offer a comprehensive range of EMI mains filters that effectively eliminate unwanted signals and electromagnetic interference from the mains supply. We have developed several product series – EN2090, EN2080, EN2070, EN2060, EN2030 and EN2020 – ensuring every customer can find a filter suited to their needs. The current rating range covers models from 1A to 36A, meaning full coverage of applications from small electronic devices to demanding industrial installations. In the product designations, you will find the variants F and S, which indicate different connector options and mounting configurations – for example, the F variant is suitable for standard connections, whilst the S variant offers alternative solutions for specific requirements. Whether you need an EMI filter for home audio equipment or for an industrial control cabinet – you’ll find the right product in our range.
Which EMI filter model should you choose for your application?
Choosing the right EMI filter depends primarily on the rated current of the device you wish to protect. Filters with ratings of 1A–6A are ideal for small electronic devices, such as power supplies for LED lighting, measuring instruments or audio equipment. If you are planning an installation for medium-sized applications, opt for the 10A–16A models. For high-current industrial applications involving machinery and automation, we recommend 20A–36A filters from the EN2070 or EN2060 series. Remember to allow for a safety margin – choose a filter with a rated current 20–30% higher than the device’s actual power consumption. When choosing between product series, also consider the requirements for high-frequency interference suppression – the EN2070 and EN2080 series offer advanced specifications for more demanding applications.
Key technical specifications of EMI filters
All mains filters in our range operate within a voltage range of 110–250 V AC/DC, ensuring compliance with various mains standards used worldwide. The two-stage filter design guarantees effective attenuation of both symmetrical and asymmetrical interference across a wide bandwidth ranging from several tens of kHz to hundreds of MHz. The models are equipped with 6.3 mm pitch screw terminals, which allow for secure cable connections and easy installation within the device housing. The compact dimensions of the individual models allow for flexible integration even in confined spaces. The internal design, based on chokes and capacitors, effectively reduces noise and electromagnetic fields penetrating the power supply line. The reliability of the components is confirmed by compliance with European EN standards, which guarantees predictable performance over many years of operation.
EMI filters in industrial and commercial applications
EMI filters are a key component of switching power supplies, inverters and industrial systems that generate significant electromagnetic interference. Installation in switchboards and control cabinets is straightforward thanks to screw terminals, which ensure stable connections even in the face of the vibrations and shocks common in manufacturing environments. The use of a suitable filter directly translates into the operational stability of machinery, automation systems and control devices – eliminating interference from the mains supply prevents communication errors and the malfunctioning of sensitive circuits. To meet EMC standards in an industrial environment, a mains filter is often an essential component of the installation. Customers seeking solutions for heavy-duty applications should consider the EN2070-36-S or EN2060-30-S models, which combine high current handling capacity with advanced attenuation performance. Additionally, the filters’ metal housing provides shielding against radiated electromagnetic fields and resistance to mechanical damage.
EMI filters in domestic and office equipment
EMI filters are widely used in electronic equipment for the home and office environments. Audio-video devices, such as amplifiers and receivers, benefit from a marked improvement in picture and sound quality thanks to the elimination of low-frequency and high-frequency interference seeping in from the mains supply. Computer power supplies are a well-known source of noise – an EMI filter effectively blocks these unwanted signals from spreading to other devices connected to the same power line. Medical and measuring equipment requires a particularly clean power supply – a suitably selected filter guarantees stable readings and reliable operation. For installations in confined spaces, we recommend compact models from the EN2030 or EN2060 series with lower current ratings. Protecting sensitive electronic circuits from electromagnetic interference extends the equipment’s service life and minimises operational issues.
