Direct current

Protect your installation against line-conducted interference with DC filters

FEAS offers DC filters for direct current (DC) and alternating current (AC) mains. They suppress line-conducted interference that can lead to errors in signal transmission. The DC filters effectively attenuate the interference pulses and interference voltages, regardless of where they originate. 
The built-in overvoltage protection diverts the unwanted transients. The careful combination of chokes and capacitors ensures effective interference suppression over a wide frequency range.

Direct voltage filters (DC filters) for DC mains

The DC filters for DC networks are connected between the DC voltage source and the load to be protected.

DC filters for AC mains

The DC filters for AC networks improve the efficiency of electric motors and transformers, for example, because they remove the DC component from the AC supply and thus ensure better transmission.

DC filters - robust thanks to full encapsulation

Fully encapsulated, the filter modules allow use even under the most adverse conditions. Whether high humidity, extreme contamination or even strong vibrations, the entire electronics are ideally protected in the compact polycarbonate or aluminium full enclosure.
The DC filters thus meet the requirements of automation technology and mechanical engineering in particular and fulfil all the necessary international standards according to VDE, EN, UL and CSA.
