The CUI Inc. PBO-1-S9 is an AC-DC power supply from the PBO-1 series, designed for board mount applications. It provides a single 9V DC output with a maximum current of 555mA, delivering up to 1W of continuous power.
This converter operates with a wide input voltage range of 85 to 305 VAC or 70 to 430 VDC, and a frequency range of 47 to 63 Hz. Key electrical specifications include a typical efficiency of 67% at 230 VAC input, line regulation of ±1.5% at full load, and load regulation of ±3% for other models. It also features over-current and short-circuit protection with auto-recovery.
The PBO-1-S9 is housed in a compact 12-SIP module with 6 leads and is designed for Through Hole mounting. It operates within an ambient temperature range of -40°C to 85°C with derating. Safety approvals include CB Scheme, EN, IEC, and UL, with an isolation voltage of 3,000 Vac.
