New low profile U-channel PSU for space-critical medical, industrial and ITE applications

20-05-2019 | XP | Power

XP Power has launched a new range of 180W U-channel AC/DC power supplies that are designed for space-constrained medical (BF), industrial and IT applications. The low-profile devices are only 29.5mm high and use a small 107.6mm x 62.8mm footprint, enabling them to be employed in high-density designs. The units are ideal for Class I and Class II operation and provide 2 x MOPP of isolation while giving up to 94% efficiency.


The UCP180 series PSUs have an integrated 12V, 500mA fan output, eliminating the need for any external driver circuitry. When used in conjunction with a fan delivering 10CFM airflow, they can deliver 180W of power to a load – a power density of 14.2W/in<sup>3</sup>. They are also suited for use in convection cooled applications where they deliver 120W (9.4W/in<sup>3</sup>). The U-channel construction provides a robust housing, an optional cover is available for applications where the unit may be user-accessible.


Suitable for medical (BF) applications, the PSUs are approved to EN60601-1 and offer 2 x MOPP of isolation (4kV) and low leakage current (50µA), making them suitable for use in BF applied part applications. Additional approvals, including IEC60950-1-1 and IEC62368-1, and EMC performance that satisfies EN61000-4, make them ideal for a broad range of applications including ITE and industrial.


There are a total of seven variants offering single outputs of 12V, 15V, 18V, 24V, 28V, 36V and 48V in the series. All devices have a universal input range of 85 to 264VAC and offer up to 94% efficiency while consuming <0.5W with no load. The operating temperature range is -40C (-20C for 180W load) to +70C with no derating needed below +50C in either force cooled or conduction cooled applications.
