Versatile Medical Class II EMC/EMI Filter
Medical filter suitable for compliance with
Protection Class II (ME) according IEC 60601-1
Approvals & Compliances
Fulfills the requirement for two MOPP (means
of patient protection), compliant with IEC/EN
60601-1
No leakage current to earth
Rated currents up to 15 A
Excellent performance/size ratio
Front mount, rear mount and snap-in versions
(B, MB and S1B type)
Plastic enclosure for higher dielectric strength
insulation
Fast-on terminals or wire leads
V-lock compatible
The FN9274 IEC inlet filter is suitable for compliance
with Class II ME equipment. It incorporates an EMC
filter into a C18 IEC inlet that offers excellent filter
attenuation in a compact housing.
The filter is available with two connection variants on
the load side. The cable version is touch-safe by
default. The pins of the fast-on-version are recessed in
the plastic housing. In combination with insulated
crimp connectors Class II compliance can be
achieved for Fast-on version.
The requirements for Two MOPP in IEC 60601-1:2005
+ A1 regarding Leakage Currents, Insulation and Air
Clearance and Creepage Distances and Ball Pressure
test are fulfilled.
