New baseplate cooled AC/DC power supply for rugged applications with limited or no airflow

The new units are intended for use in semi-conductor manufacturing and industrial technology applications including test and measurement, factory automation and process control, with a focus on solving cooling, air pollution and integration issues.

The new ASB160 series are compact and complete AC/DC power supplies that include an EMC filter, AC fuse and bulk storage capacitor, making them ready for direct-to-PCB installation into an end application where they can operate with a baseplate temperature in the range -40°C to +90°C.

ASB160 units can operate globally due to the universal input range of 90 to 264VAC and the series offers a total of six single DC output voltages 12, 15, 24, 36, 48 and 54VDC.

Housed in a full brick baseplate cooled module, the compact devices measure just 2.40 x 4.60 x 0.78”. This, along with efficiency levels up to 93%, achieves some of the highest power density levels currently available in this type of device. As such, the rugged units are suitable for use in sealed enclosures including ATEX approved equipment as the baseplate cooling removes any need for forced air / fan cooling.

As a complete solution, the ASB160 modules offer inbuilt protection mechanisms including over current, over voltage and over temperature. Effective heat removal via the baseplate ensures elevated levels of reliability and ease of integration.

The ASB160 series is available from Digi-Key, Distrelec, Farnell, Mouser, RS Components, approved regional distributors, or direct from XP Power and offers a 3-year warranty.
