XP Power has launched a range of 180 W U-channel AC/DC power supplies that are intended for space-constrained medical (BF), industrial, and IT applications. The low-profile devices are just 1.16" high and occupy a small 4.3" x 2.5" footprint, allowing them to be used in high-density designs. The units are suitable for Class I and Class II operation and offer 2x MOPP (means of patient protection) of isolation while delivering up to 94% efficiency.

The UCP180 series PSUs have an integrated 12 V, 500 mA fan output, eliminating the need for any external driver circuitry. When used in conjunction with a fan delivering 10 CFM airflow, they can deliver 180 W of power to a load, a power density of 14.2 W/in³. They are also suited for use in convection-cooled applications where they deliver 120 W (9.4 W/in³). The U-channel construction provides a robust housing, and 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 2x MOPP of isolation (4 kV) and low leakage current (50 µA), making them suitable for use in BF applied part applications. Additional approvals including IEC60950-1-1 and IEC62368-1, and EMC performance that meets EN61000-4, make them suitable for a wide range of applications including ITE and industrial.

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