depicted in the derating curves shown below. All devices, when operated at full
load, in still ambient air, over their full specifi ed input voltage range, can safely
operate to T
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.
