New low leakage current filters satisfy market demands

09-10-2023 | Schaffner Holding AG | Power

Schaffner’s new FN304X series of low leakage current filters fill a notable gap in the robotics market and other industrial applications for low-profile three-phase filters.

Predicting supply challenges creating hurdles in the market, the company developed flexibility in its manufacturing processes to mitigate this impact, resulting in the high availability of its new low-leakage current filters. The FN3040, FN3041, FN3042 and FN3043 EMC filters are rated for currents of 10A–30A at 50C. Produced particularly to satisfy customer demands, the tight-packaged filters are smaller than their predecessors yet deliver superior performance in different levels (Ferrite or Nano Crystalline versions). Flexible design possibilities are available thanks to the embedded terminals being straightforward to connect and optional (FN3042 / 43) DIN Rail mounting.

Created to meet the particular EMC conditions of the European market, the filters are particularly suited to grids with very tough conditions and other applications with safety and reliability as a main focus. A plastic housing combined with a metal ground plate attains the lowest possible product weight without compromising EMC behaviour, while fixed, hinged terminal covers enhance safety levels by protecting against contact with live conductors.

Other industry-standard form factor filters features include leakage current between 0mA and 0.4mA depending on voltage level and inductance from 0.5mH to 12.9mH at 1kHz.

The new low-leakage current filters are ideal for robotics, electrical and electronic equipment, industrial automation, test and measurement devices and small machines. Designed with sustainability in mind, the filters feature raw materials that can be readily separated at the end of the product’s working life for environmentally safe disposal.
