Radiated Emissions
If you’re designing with EMC in mind, please note that all of DATEL’s
LSN D12 DC/DC Converters have been characterized for conducted and
radiated emissions in our EMI/EMC laboratory. Testing is conducted in an
EMCO 5305 GTEM test cell utilizing EMCO automated EMC test software.
Conducted/Radiated emissions are tested to the limits of FCC Part 15, Class
B and CISPR 22 (EN 55022), Class B. Correlation to other specications can
be supplied upon request. The corresponding emissions plots to FCC and
CISPR 22 for model LSN-5/10-D12 appear below. The published EMC test
report is based on results with the highest possible output power model and
is therefore representative of the whole LSN-D12 series. Contact DATEL’s
Applications Engineering Department for more details.
