The PBO series of ultra-compact 3-W and 5-W ac/dc power supplies are available in an open-frame SIP package. They measure as small as 35 x 11 x 18 mm. The 3-W models are available in low-profile, right-angle versions measuring as small as 35 x 18 x 11 mm, making them suitable for applications in which vertical board space is at a premium. Typical efficiencies are up to 80%, with input voltage ranges of 85 to 264 Vac or 70 to 400 Vdc. Single-output voltages of 3.3, 5, 9, 12, 15, and 24 Vdc are available. The 3-W models offer a wide operating temperature range of –40°C to 85°C, while the 5-W models provide a range from –25°C 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 overcurrent and short-circuit protections. The power supply boards target industrial systems, automation equipment, security, telecommunications, and smart home devices.
