from a standard 1" x 2" package, and these power converters exemplify DATEL’s

relentless drive to bring you more power/current, from standard packages, without

compromising reliability or resorting to thermal specmanship.

standard 2" x 1" package from which most competitors can only get 5-10W (@

3-4A). All UWR’s deliver their full output power over ambient temperature ranges

from –40°C to as high as +70°C (model and input voltage dependent) without heat

sinks or supplemental forced-air cooling. Devices derate to +100°C.

... 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 ...
