Application Example
500, family attenuation process S.M.P.S.
shows conducted emissions switched mode power supply which suppression components.
conducted emissions exceed standards from over MHz.
effect inserting choke line seen Fig.
Below narrowband differential mode peaks have been significantly reduced. Differential mode suppression strong point from choke series 500.
significant reduction emissions also noted above MHz.
choke self resonance frequency increase emissions noted reduce this effect other suppression components would used. using thischoke with other components complete suppression this power supply achieved shown
suppression device
Multilevel attenuation Process S.M.P.S.
Usage dedicated discrete suppression devices, like symmetrical mode attenuation chokes 500, series) and/or asymmetrical mode attenuation chokes, 100, series) and/ capacitor suppression network 9223, 223) allow designer build multistage filtering. Each stage works specific frequency area, noise mode, fig.
This added flexibility been made feasible with proper design above mentioned Schaffner product families. Build work together optimized perfect interaction, this combined with freedom select capacitance inductance values they allow fast efficient design high volume production equipment example result shown fig.

Care must course taken ensure that convention observed.
Example selection storage chokes:
Consider simple Buck converter with shown values:
higher switching frequencies required choke becomes smaller, however there increased likelihood higher interference levels
using frequency medium sized choke used harmonic which just below critical frequency harmonic over kHz. There need large suppression elements. advantage small storage elements lost increase filtering requirements.

What
(International Electrotechnical Commission) governmental organisation responsible preparing standards recommendations Electrotechnical Industry, like (International Standards Organisation) most other area activities.
standards recommendations adopted regulations national international bodies such VDE, their respective countries CENELEC Normalisation Electrotechnique) cover member states (European Community).
safety recommendation covering "Information Technologie" "Electrical Business" machines Therefore covers: small large computers, faxes, copiers, typewriters many other types equipment available business environment
does specifically mention power line filters filters components most above mentioned equipment, several aspects have direct effect power line filters design, test, measurement specifications.
Specifications what they?
Schaffner compatible filters fulfill requirements following way:
BASIC SUPPLEMENTARY INSULATION power distribution systems.
High potential tests rated 2,125 (1500 test recommended capacitor reliability reasons) this phase neutral, phase housing, neutral housing. Test duration sees system qualification level, well component qualification level. production equipment filter this test only carried more rated value.
leakage current
Schaffner filters have been designed produce less leakage current than maximum permitted most cases, allowance additional leakage from equipment included. This meet mobility equipment type class
discharge time
filters have phase neutral discharge less than second. This meets requirements classes equipment, pluggable well permanently installed.
your system tested approved?
Approving equipment with power line filters implies system test 2125 1500 VAC) test sees. During these tests discharge resistors, when they exist, many times overloaded allows this test carried without these resistors.
such tests, filter without discharge resistor supplied. They xxxxT types. require special units system tests
Filters other requirements
other requirements such test reinforced insulation test earth "IT" earthing applications, please contact your nearest Schaffner sales office obtain specially designed specified
filter based original standard type. Please note that changes dimension result increased insulation requirements.
