Low Profile, Medical/Industrial/IT 180W U-Channel PSU

XP Power launched a new range of 180W U-channel ac-dc power supplies intended for space-constrained medical (BF), industrial and IT applications. The low-profile devices are just 1.16in high and occupy a small 4.3in x 2.5in footprint, allowing their use in high-density designs.

The power supplies are suitable for Class I and Class II operation, and they offer 2 x MOPP (Means of Patient Protection) of isolation while providing up to 94% efficiency.

With an integrated 12V, 500mA fan output, the series eliminates the need for any external driver circuitry. When coupled with a fan delivering 10CFM airflow, they can provide 180W of power to a load. This output translates to a power density of 14.2W/in³. The units are also suited for use in convection cooled applications where they deliver 120W (9.4W/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) applied part applications, the PSUs are approved to EN60601-1 and offer 2 x MOPP of isolation (4kV) as well as low leakage current (50µA). Additional approvals including IEC62368-1 and IEC60950-1-1, and EMC performance that meets EN61000-4 make them suitable for a broad range of applications including industrial and ITE.

A total of seven variants offer single outputs of 12V, 15V, 18V, 24V, 28V, 36V and 48V in the series. All the devices feature a universal input range of 85Vac 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.
