... By combining a high-frequency, high-effi ciency (to 88%), synchronous-rectifi er topology with the newest components and time-tested, fully automated, SMT-on-pcb construction, these UWR Models are able to bring you 7-15W (@ up to 6A) in the standard 2" x 1" package from which most competitors can only get 5-10W (@ 3-4A). All UWR’ ...

... Certain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. Fuses should also be used if the possibility of sustained, non-current-limited, input-voltage polarity reversals exists. For DATEL A-Series UWR 7-15 Watt DC/DC Converters, you should use slow-blow type fuses with values no greater than the following. V ...

... All models, other than the D12A models A (10-18 Volt input range), can operate at higher ambient temperatures if the input range is narrowed. For example, model UWR-5/3000-D48A can operate safely to +70°C if the input range is kept between 36 and 48 Volts. Contact DATEL's Applications Engineering Group if you need additional details. ...
