ASB Series AC/DC Power Supplies

XP Power’s Compact, conduction-cooled AC-DC power supply module for challenging and space-critical applications

Image of XP Power's ASB110 Series AC/DC Power Supply XP Power's ASB75 series of half brick and ASB110 series of full brick, baseplate cooled AC/DC power supplies require no external circuitry for operation or EMC compliance. Models offer compact, fanless power with baseplate cooling for applications such as information technology equipment (ITE), Internet of things (IoT), general industrial, and harsh or rugged applications.

The complete AC/DC power supplies deliver up to 75 W (ASB75) or 110 W (ASB110) of power from a universal (90 VAC to 264 VAC) input. They feature an integral AC fuse, EMC filter, and hold-up capacitor, which simplifies integration and requires less space.

ASB devices feature baseplate cooling, thereby enabling operation in sealed metal enclosures using passive cold wall cooling to transfer any heat to the outside of the equipment. An optional heatsink is also available pre-mounted or separately, allowing designers to use conventional convection or forced air cooling where preferred.

There are six models in the range, offering single output voltages of 12 V, 15 V, 24 V, 28 V, 36 V, or 48 V. Efficiency levels as high as 90% minimize unwanted heat generation and contribute to an excellent power density within an industry-standard package.

The units offer EMC compliance as standard with no external components required to meet EN55032 Level B for conducted and radiated emissions and offer immunity to meet EN61000-4. Safety compliance to UL/EN/IEC62368-1 also comes as standard.

The rugged, encapsulated devices have built-in protection for overtemperature, overcurrent, overvoltage, and output short-circuit, thereby protecting the device as well as any load that it is powering.

A baseplate operating temperature of -40°C to +85°C ensures that ASB devices are suited to a wide range of application environments. At the same time, full encapsulation increases reliability in harsh environments and applications that require rugged devices.
