XP Power has rolled out the SDL400 series of 400W 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 39.9mm 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 220W for the single output models.

With a peak power output of up to 700W for up 0.5s, the SDL400 is ideal for applications that have high power demands for short duration loads such as starting up a motor. Single output models are available with the popular nominal outputs between 12 and 48VDC, as well as both a 54 and 60VDC output variant. Dual output models have a 5VDC output in combination with a 12, 24 or 48VDC or a 12 / 24VDC model. The output voltage V1 can be manually trimmed ±5 per cent 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°C, and with derating up to 70°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 (500µA) is available by adding -L to the part number.
