UWR Series
Single Output, High Reliability, 2" x 2", 14-20 Watt, DC/DC Converters
Typical Performance Curves (TA = +25°C)
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.

EMI RADIATED EMISSIONS
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.
