Desktop External AC-DC Power Supply Series

CUI Desktop External AC-DC Power Supply Series has been expanded to meet the more stringent average efficiency and no load power requirements to meet Level VI efficiency standards. The external power supplies feature a wide universal input voltage range of 90-264Vac and are available in single output voltages of 12, 15, 16, 18, 19, 24, and 48Vdc depending on the series. They offer UL/cUL, GS, and PSE safety approvals and meet the radiated and conducted emission requirements for FCC Part 15B Class B. Additional features include power factor correction as well as over voltage and short circuit protections.
