A-Series DC/DC Converters have been characterized for radiated and con-
ducted emissions in our new EMI/EMC laboratory. Testing is conducted in
an EMCO 5305 GTEM test cell utilizing EMCO automated EMC test software.
Radiated emissions are tested to the limits of FCC Part 15, Class B and
CISPR 22 (EN 55022) Class B. Correlation to other speci?cations can be
supplied upon request. Radiated emissions plots to FCC and CISPR 22 for
model TWR-5/3000-15/500-D12A appear below. Its performance is typical
of all models in the Series. Published EMC test reports are available for
each model number. Contact MPS’s Applications Engineering for details.
