Baseplate cooled AC-DC power supplies deliver 110W

April 09, 2015 // By Graham Prophet
XP Power’s ASB110 series provides a complete AC-DC power supply module requiring no external components. The full brick sized power supplies offer very high efficiency and a low profile for PCB pin mounted designs.

Aimed at ITE and industrial customers looking for a base plate cooled power supply solution, the ASB110 provides 110W of DC output power from a universal AC input. Its efficiency of 91% limits the heat to be dissipated by the heatsink or base plate. No external components are required as the units include EMC filtering, bulk storage capacitors and an AC input fuse. The ASB110’s low profile, full brick package measures 116.8 x 61.0 x 17.0mm. Cooling can be accomplished by mounting the device to, for example, the host equipment’s metal chassis or by adding an optional heatsink.

Six single output models are available in standard outputs of 12, 15, 24, 28, 36 and 48VDC. The power supplies feature a no-load power consumption of less than 0.3W maximum, which together with their high efficiency meets XP Power’s Green Power requirements. Standard protection includes over current, over voltage and over temperature, and a universal input range of 85 to 264 VAC is provided for.

With an operating temperature range of -40 to +85C the range is suitable for use in applications where an extended operating temperature range is required. The ASB110 series have ITE 60950-1 international safety approvals per UL, TUV and CB agencies, and meet Class B emissions standards as per EN55022 without the need for additional filtering components.

The ASB110 series is available from Farnell, element14, Digi-Key, approved regional distributors, or direct from XP Power and come with a 3 year warranty.
