Open frame AC/DC power supplies ideal for space-constrained applications
CUI has announced a family of ultra-compact AC/DC power supplies in an open frame SIP package. The 3W and 5W configurations of the PBO series measure as small as 35mm x 11mm x 18mm, allowing them to occupy less board real-estate than other power solutions. The 3W models are also available in low-profile, right-angle versions measuring as small 35mm x 18mm x 11mm , making them ideal for applications where vertical board space is at a premium.
Available with typical efficiencies up to 80%, the high density PBO series offers a wide input voltage range of 85 to 264VAC or 70VDC to 400VDC for high voltage DC-DC systems. Single output voltages of 3.3, 5, 9, 12, 15 and 24VDC are available depending upon the series. For use in challenging environments, the 3W models offer a wide operating temperature range of -40C to +85C while the 5W models provide a range from -25C to +85C. Additionally, all models are designed to provide 3,000VAC 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 ultra-compact models are ideally suited for a variety of applications including industrial systems, automation equipment, security, telecommunications and smart home devices.
