Open frame AC/DC power supplies for space constrained apps

CUI has announced a family of compact AC/DC power supplies in an open frame SIP package. The 3W and 5W configurations of the PBO series measure 35 x 11 x 18mm and the 3W models are also available in low-profile, right-angle versions measuring 35 x 18 x 11mm, making them suitable for applications with little vertical board space.

Available with typical efficiencies of up to 80%, the high density PBO series offers an input voltage range of 85 to 264V AC or 70 to 400V DC for high voltage DC/DC systems. Single output voltages of 3.3, 5, 9, 12, 15 and 24V DC are available depending upon the series.

The 3W models function in temperatures ranging from -40 to 85°C while the 5W models provide a range from -25 to 85°C.Additionally, all models are designed to provide 3kV AC input to output isolation.

The PBO series also meets UL60950-1/EN 60950-1 standards, complies with EN55022 Class B limits for conducted and radiated emissions and includes over current and short circuit protections.

The models are suited for a variety of applications including industrial systems, automation equipment, security, telecommunications and smart home devices.
