XP Power’s ASB110 series provides a complete baseplate-cooled AC-DC power supply module that requires no external components in an industry standard full brick, low profile package. Aimed at ITE and industrial customers looking for a baseplate-cooled power supply solution, the ASB110 provides 110W of DC output power from a universal (85 – 264VAC) AC input. 


Its high efficiency of up to 91% means that the heat to be dissipated by the heatsink or base plate is minimal. No external components are required as the units include EMC filtering, bulk storage capacitors and an AC line input fuse. The ASB110’s low profile, full brick package measures just 116.8 x 61.0 x 17.0mm and cooling can be accomplished by mounting the device to the host equipment’s metal chassis, including applications in sealed enclosures, or by adding an optional heatsink.


For versatility, 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 resulting in less wasted heat and a product that is better for the environment. Standard protection includes over current, over voltage and over temperature.


With an operating temperature range of -40 to +85 degrees C, at the module baseplate, the product is ideal for use where an extended operating temperature range is required such as sealed enclosures and outdoor applications. The ASB110 series has ITE 60950-1 international safety approvals per UL, TUV and CB agencies and Class B emissions standards per EN55032 without the need for additional filtering components.


The ASB110 will find favor with end users in automation, process control, broadcast, fixed telecom, instrumentation, mobile communications, specialist equipment and transportation market areas. Calling on XP Power’s considerable in-house experience and knowledge, careful consideration of component selection and PCB layout design has resulted in the ASB110, a power supply that offers 110W output in a full brick format with pin mounting for PC boards.  With its high efficiency and low profile, it is the ideal choice for space-constrained applications.
