Double-insulated single-phase EMC filter for industrial and medical power applications introduced by SCHURTER
SANTA ROSA, Calif. – SCHURTER Inc. in Santa Rosa, Calif., is introducing the IEC protection class II FMAB NEO single-phase electromagnetic compatibility (EMC) power filter for applications such as critical medical systems and in-home medical devices that provide user protection from electric shock through two levels of insulation without the need for earthing.
This double-insulated filter with no protective ground offers insulation safety testing, low leakage current, and high attenuation performance of electromagnetic interferences -- particularly symmetrical attenuation.
According to IEC 61140, the term IEC protection class II is also referred to as protective insulation. It is further defined as protection by doubling or reinforcing insulation of live parts.
All clearances and creepage distances must be doubled, requiring that the inside of the filter also has double or reinforced insulation. The FMAB NEO for Class II meets all these requirements, with reinforced insulation inside of the filter and large plastic collars around the terminals.
Additionally, the filters are hi-pot tested with four-kilovolt AC (kVAC) between L or N against the metal housing for a dielectric strength of more than 5.6 kilovolts DC (kVDC), according to IEC 60601-1.
Leakage current ratings of less than 5 amperes are available. Other applications for the FMAB NEO include industrial equipment, laboratories, telecommunications, audio/video, and office equipment.
The FMAB NEO for IEC protection class II is rated 1-20 amps at 250 volts AC according to IEC and 125 and 250 volts AC according to UL.
