If you can not find on this list your desired type, so please check with us.

We have the right footprint filter for your inverter!

Standards

The inverter-filter combinations are designed and tested to comply with the limits of the following standards mentioned: DIN EN 61800-3 “Adjustable speed electrical power drive systems – EMC requirements and test methods” and DIN EN 55011 “Industrial, scientific and medical radio-frequency devices (ISM devices) – radio disturbance characteristics – Limits and methods of measurement”.

Technical Information

For further information please contact the separate datasheets for each filter series available. There you will find the dimensions, the filter circuits and the electrical data.

Leakage current

Especially in single-phase applications, increased leakage current is present. For three phase applications, the leakage is very low under normal conditions (symmetry of the three phases). The highest values ​​occur when switching on or in the absence of one or two phases. All NF-U grades are available on request as a “low leakage current version”.
