XP Power today 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 39.9 mm (1.6 inches) 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 air flow, 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.
Single output models are available with the popular nominal outputs between +12 and +48 VDC, as well as both a +54 and +60 VDC output variant. Dual output models have a +5 VDC output in combination with a +12, +24 or +48 VDC or a +12 / +24 VDC model. The output voltage V1 can be manually trimmed +/-5% with the dual’s V2 output tracking by the same percentage of adjustment.
The SDL400 series has an operating temperature range from 0 to +50 degrees C, and with derating up to +70 degrees C. Overvoltage, overload and short circuit protection are standard features. Additionally, all models have remote on/off, power good and fan fail signals. The units meet EN55022 class B conducted and radiated emissions. Safety agency approvals are per UL 60950-1, CSA 22.2 No. 60950-1 and EN 60950-1 standards.
A low leakage current option (500 µA) is available by adding –L to the part number.
The SDL400 is available from Farnell, element14, approved regional distributors, or direct from XP Power and come with a 3 year warranty.
