Electromagnetic Emission
The conducted noise emitted at the input in the frequency
range of 10 kHz to 30 MHz is below level B according to
EN 55011/22 under all operating conditions.
The radiated noise in the frequency range of 30 MHz to
300 MHz on the input- and the output-side stays below the limit
of EN 55014, measured with an MDS-clamp and below level A,

according to EN 55011/22, measured with an antenna.
The radiated noise of the T units between 30 MHz and
1 GHz is reduced, if the converter is built into a conductive
chromatized 19" rack, fitted with a front panel. For converters
mounted otherwise, e.g., wall mounted with option B1 (base
plate), the radiated noise may be above level A.
protection against input transient voltages, which typically
occur in most installations, but especially in battery-driven
mobile applications. The T Series has been successfully
tested to the following specifications:
