CUI Inc., has introduced the PBO series, a family of very small AC-DC power supplies in an open-frame board-mount package.
Available in versions with a maximum power- output rating of 3W or 5W, the PBO series’ package measures as little as 35mm x 11mm x 18mm. The 3W models are also available in a low-profile, right-angle version just 11mm high, making them suitable for applications in which vertical space above the surface of the board is at a premium.

For use in challenging environments, the 3W models offer a wide operating-temperature range of -40°C to 85°C, while the 5W models operate from -25°C to 85°C. Additionally, all models provide input-to-output isolation of 3kV AC.

Single output voltages of 3.3V, 5V, 9V, 12V, 15V or 24V DC are available depending upon the series.

The PBO series conforms to the requirements of the UL60950-1/EN 60950-1 standards, and meets the EN55022 Class B limits for conducted and radiated emissions.
