EMI filter 8020 series

power linefor shielded enclosurescompact

The Compact high-performance power line filters are capable of providing a radiated transmission loss of 100 dB at 14 kHz up to 40 GHz. The leakage current is in milliampere level and the voltage drop is less than 1 V. The filter is made to withstand the harshest environment and is very economical. Because of the custom design for your own filter, the assembly is very simple and always with very low leakage. This filter is also a stock item and therefore always available quickly. This series is offered as a two-line filter (single-phase and neutral) or as a four-line filter (three phases and neutral). The single-phase filter can withstand up to 277 Volt, 1-1000 amp. If you are looking for a filter that can withstand more power we have the three-phase filter, this filter delivers up to 480 Volt, 1-1600 amp. The neutral line is always attenuated and all conductors are decoupled from each other. This allows the conductors to operate independently without attenuation loss. The circuit is designed as a symmetrical double-circuit with high-quality rod cores providing inductance. These cores do not saturate due to their large air gap and they are insensitive to asymmetrical load. Foil capacitors ensure a long operating life by their self-healing features even after voltage transients. A seamless fixing of the filter casing to the shielded room is very important to ensure the correct operation. The filter is housed in a casing that has a base flange which provides stable mounting and excellent earthing when bolted to the shielded room via the mounting bolts.
