XP Power has launched a new range of 180 Watt U-channel AC-DC power supplies (PSU) that are intended for space-constrained medical (BF), industrial and IT applications. The low-profile devices are just 29,5 mm high and occupy a small 107,6 x 62,8 mm footprint, allowing them to be used in high-density designs. The units are suitable for Class I and Class II operation and offer 2 x MOPP (Means of Patient Protection) 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. They are also suited for use in convection-cooled applications where they deliver 120 W. 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 applications, the PSUs are approved to EN60601-1 and offer 2 x MOPP 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 IT and industrial.
There is a total of seven variants in the series offering single outputs of 12 V, 15 V, 18 V, 24 V, 28 V, 36 V and 48 V. All devices have a universal input range of 85 to 264 V a.c. 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.
