Interference filter
Our high protection level filters for 230/400 V distribution networks are designed to protect supply and control cables against EMP interference in telecommunications, research, measuring and medical applications. We can make custom and special solutions too.
EMI-filter for power supply cables
Filtro Oy has a long experience in designing and manufacturing EMI-filters. Our filter series consist of tens of different power supply filters, capable to protect different electric and electronic devices in case of EMP (NEMP) pulse, lightning or microwave frequency interference.
Filters for data, control and alarm cables are part of Erikois-Elektroniikka OY's product range.
Interference filter for low voltage distribution networks
EMP-filters for 230/400Vac power supply networks, ranging from small 2-pole 1-phase filters for control cables, to 4-pole 400A 3-phase filters.
Interference filter fo DC-applications
Standard filters for DC-supplies range from 0,5A to 63A currents.
DC-filters protect rooms in medical applications and hospitals, fixed or mobile computer and communication centrals, and vehicles for communications.
In addition to old communication stations and command centrals, DC-filtration has an important role in mobile stations and exchanges.
Standard interference filters
In case of non-standard EMPF-filter is required, either mechanically or electrically, we can offer custom solutions.
