Ultra-Compact Open Frame AC-DC Power Supplies

Ultra-Compact Open Frame AC-DC Power Supplies

CUI Inc announced a family of ultra‑compact ac-dc power supplies in an open frame SIP package. The 3 W and 5 W configurations of the PBO series measure as small as 35 x 11 x 18 mm (1.38 x 0.43 x 0.71 in), allowing them to occupy less board real-estate than other power solutions. The 3 W models are also available in low-profile, right-angle versions measuring as small 35 x 18 x 11 mm (1.38 x 0.43 x 0.71 in), 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 264 Vac or 70 to 400 Vdc for high voltage dc-dc systems. Single output voltages of 3.3, 5, 9, 12, 15 and 24 Vdc are available depending upon the series. For use in challenging environments, the 3 W models offer a wide operating temperature range of -40 to +85°C while the 5 W models provide a range from -25 to +85°C.  Additionally, all models are designed to provide 3,000 Vac 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.
