HT Series
The HT series power line filters provide superior common-
mode and premium differential-mode attenuation to RFI
noise on the frequency range from 10kHz to 30MHz, for
IEC 60601 and UL2601 patient-connected equipment, as
well as all other electronic equipment that cannot tolerate
leakage current.
They are a size- and cost-effective solution to the problem
of meeting both medical leakage current limits and
conducted emissions limits in equipment with high noise
sources (such as switching power supplies). HT series
filters can meet the following Conducted Emissions
standards:
• European Normalized Standards based on EN55022,
Level A (in many cases, Level B also).
• FCC Part 15, Computing Devices, Class B.
• FCC Part 18, ISM Equipment, Industrial and
Consumer.
Note: When using the models with an IEC connector,
remember that the leakage current of the companion line
cord, GA400, is more significant than that of the filter -
which may disqualify this line cord from use in patient care
applications.
For more information on UL2601, see Appendix C.
