XP Power has announced the SDL400 series of 400 Watt single and dual output AC-DC power supplies. These compact units, suitable for 1U applications, are available in four mechanical formats: U channel, U channel with cover (-C option), top fan cover (-F option) and end fan cover (-E option). All of the formats apart from the top fan mounted version are less than 1.6 inches (39.9 mm) high. A variable speed fan is used to reduce audible noise at lower load conditions and extend fan life in the –E and –F models. For applications without a fan or forced airflow, the units can operate with convection cooling up to 220 W for the single output models.
With a peak power output of up to 700 Watts for up 0.5 s, the SDL400 is ideal for applications that might have a higher power demand for short duration loads such as starting up a motor. This capability saves designers from having to specify a larger, more expensive power supply to satisfy this requirement.
