Schaffner, the international leader in the fields of electromagnetic compatibility and power quality introduce announce the release of a complete range of their popular FN3280H 4-Line filter series featuring higher insulation resistances.
The FN3280H is a compact and lightweight filter design with a “cubic“ shape requiring minimum mounting space, simplifying the power entry design of enclosures and control panels for machine builders.
The new line-up of FN3280H filters, with the so-called R69 option, will not cause the overall insulation resistance of machinery or equipment when under test to drop below 1MΩ, ensuring systems fitted with the new EMC filter will comply with European and International safety standards. The filters also increase EMC immunity if connected directly to the mains input.
As a mains input filter for equipment requiring 3-phase power with a neutral line, the FN 3280 provides enough performance to ensure EMC compliance of machinery in mixed (Class A) or even domestic (Class B) environments while also increasing the immunity of the entire installation significantly. The new filter series is now available with power ratings up to 600A and the line-ground discharge time (after power disconnection) is increased so that standard models may be more suitable for non-machinery applications.
The FN3280 series provides the attenuation performance needed to meet the requirements of various machine tools with up to 12 driving axes and ~10 to 20m of motor cable each. To simplify selection for an application, the filter current ratings are aligned with common fuse values. The attenuation performance is identical to standard models making them interchangeable depending on the end-product application.
Providing simple and time-saving installation with good accessibility for automatic and hand tools FN3280H filters have solid, touch-safe terminal blocks (8 to 200 A types) offering sufficient contacting cross-section according to the EN 60204-1 installation standard, commonly required for industrial applications.
Key specifications include maximum continuous operating voltage 3 x 520/300 Vac, operating frequency DC – 60Hz, rated currents 8 – 600A, operational temperature range -25⁰C to 100⁰C.
Typical applications include industrial equipment, machinery, machine tools and diverse process automation systems requiring 3-phase and neutral electricity supply. Due to the outstanding attenuation performance, FN3280 is also the first choice for noisy power supplies, renewable energy applications, high power office equipment etc. Because of the relatively low leakage current, FN3280 may even be used for some medical devices.
