Accessories for measuring relays

Reliable operation of measuring relays

Frequency converters are increasingly used in installations. Their output generates steep switching edges that cause significant EMC interference and high frequency compensation currents in the connected switching components. The devices connected to the converter could suffer interference or possibly be damaged. Interference suppressor filters from DOLD can ensure a wide range of interference suppression up to high frequencies. Through the intermediate switch of an interference suppressor filter between the converter and the measuring relay whose interference is to be suppressed and/or device, interference and even destruction of the connected devices is avoided.
