DATELs world-class design, development and manufacturing team stands
ready to work with you to deliver the exact power converter you need for your
demanding, large volume, OEM applications. More importantly . . . we’ll do
it on time and within budget!
Our experienced applications and design staffs; quick-turn prototype capabil-
ity; highly automated, SMT assembly facilities; and in-line SPC quality-control
techniques combine to give us the unique ability to design and deliver any
quantity of power converters to the highest standards of quality and reliability.
We have compiled a large library of DC/DC designs that are currently used
in a variety of telecom, medical, computer, railway, aerospace and industrial
applications. We may already have the converter you need.
Contact us. Our goal is to provide you the highest-quality, most cost-effective
power converters available.
If you’re designing with EMC in mind, please note that all of DATELs UPB
25-40 Watt DC/DC Converters have been characterized for radiated 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. Correlation to other specifications can be
supplied upon request. Radiated emissions plots to FCC and CISPR 22 for
model UPB-5/8-D48 appear below. Published EMC test reports are available
for each model number. Contact DATEL's Applications Engineering Depart-
ment for more details.
