The SDI18-5-UD-P5R is a 5V 15W AC/DC desktop power adapter manufactured by CUI Inc. Designed for commercial information technology equipment, this Class II adapter provides a stable 3A output current with a maximum ripple and noise of 100 mVp-p. It operates on a universal input voltage range of 90 to 264 Vac at 47 to 63 Hz, making it suitable for international deployment.
Engineered for efficiency, the unit meets DoE Level VI and CoC Tier 2 standards, consuming less than 0.075 W at no load. Safety features include overvoltage protection at 12 Vdc, overcurrent protection at 7 A, and auto-recovery short circuit protection. The adapter offers 3,000 Vac input-to-output isolation resistance and boasts an estimated MTBF of 300,000 hours at 25°C.
Physically, the adapter measures 88.5 mm x 50.0 mm x 34.0 mm and features a right-angle barrel plug output connector (2.1 mm ID x 5.5 mm OD x 9.5 mm). It includes a 1.50 m input cord and complies with UL/cUL, CE, PSE, and FCC Class B standards under IEC 62368-1. Operating temperatures range from 0°C to 40°C, with storage capabilities between -20°C and 80°C.
The input voltage range is 90-264 Vac at 47-63 Hz, and the output is 5 Vdc.
