The performance curves below were derived from actual test data for a
single model number (UWR-5/4000-D12A). Since all devices in the 14-20W
UWR A-Series have the same circuit topology, the performance curves are
representative of all devices.

If you’re designing with EMC in mind, please note that all of DATEL’s UWR
14-20 Watt A-Series DC/DC Converters have been characterized for radi-
ated and conducted 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. Radiated emissions plots to FCC
and CISPR 22 for model UWR-5/4000-D12A appear below.
Quality and Reliability
The A-Series are the fi rst DC/DC Converters to emerge from DATEL’s new,
company-wide approach to designing and manufacturing the most reliable
power converters available. The fi ve-pronged program draws our Quality
Assurance function into all aspects of new-product design, development,
characterization, qualifi cation and manufacturing.
