Low profile U-channel PSU for space-critical applications

A new range of 180W U-channel AC/DC power supplies has been launched by XP Power, intended for space-constrained medical (BF), industrial and IT applications. The low-profile devices are just 29.5mm high and occupy a small 107.6x62.8mm footprint, allowing them to be used in high-density designs.

The units are suitable for Class I and Class II operation and offer two MOPP (Means of Patient Protection) of isolation while delivering 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/in³.

They are also suited for use in convection cooled applications where they deliver 120W (9.4W/in³). 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 two 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 meets EN61000-4, make them suitable for a wide range of applications including ITE and industrial.

There is a total of seven variants offering single outputs of 12, 15, 18, 24, 28, 36 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 -40°C (-20°C for 180W load) to +70°C with no derating required below +50°C in either force cooled or conduction cooled applications.
