The CUI Inc. PBK-3-9 is an AC-DC power supply designed for board-mount applications. It delivers a single regulated output of 9V at up to 3W continuous power.
Key electrical specifications include a wide input voltage range of 85 to 264 VAC, an efficiency of up to 76%, and protections for over current and short circuits. The unit provides 3,000 VAC isolation between input and output.
Mechanically, the PBK-3-9 is housed in a compact 12-SIP module with 6 leads and is designed for through-hole mounting. It operates across a wide temperature range of -40°C to 85°C, with derating at higher temperatures.
This power supply is suitable for ITE (Commercial) applications and carries CE and cULus safety approvals. The part number key indicates it is part of the PBK-3 series, with '9' denoting the 9V output voltage.
