Special Filters (Customized)

Development of customized filtering solutions

For an application optimized solution in terms of radio interference and Immunity many criteria must be observed. For this reason we offer customized filters in addition to our standard solutions which meet most requirements. These were developed based on the applicable standards with regard to electrical and mechanical effects on the handling application. We can measure the compatibility of your device or system on request.

EPA is continually developing new customized filter solutions, both mechanically and electrically optimized and are thus precisely tailored to the application of our customers.

You will find a large part of the overall program of suppression components of EPA on our website . If an EMC problem mechanically or electrically can not be solved with a standard filter, so our customers have a large number of already tested special filters.

So we can offer appropriate solutions also for applications where less mounting space is available or the amount of leakage currents to earth play a significant role (e. g. the use of RCCBs). Mains filters for 690V- and IT networks are available from stock. EPA will advise you in selecting the filter actions for your application!

If you do not own measurement capabilities, you can have the necessary measurements done reliable in our laboratory accomplished by our qualified personnel without long waits.

We will be happy to help you find the best and most cost-effective solution for your application!
