The CUI Inc. SDI50-12-UD-P5R is a 50W AC/DC desktop adapter designed for reliable power conversion. It accepts a universal AC input from 90 to 264 Vac at 47-63 Hz and delivers a regulated 12Vdc output at up to 4.2A. The adapter achieves high efficiency meeting Level VI and CoC Tier 2 standards, with a maximum no-load power consumption of 0.15W.
Electrical protections include over voltage protection (latch-off at 180%), over current protection (auto-recovery at 180%), and short circuit protection (auto-recovery). The input-to-output isolation is rated at 3000 Vac minimum, with an isolation resistance of 10 MOhm. Ripple and noise is limited to 120 mVp-p under full load conditions.
The adapter operates over a 0°C to 40°C temperature range and can be stored from -20°C to 80°C. It measures 115 x 53 x 38 mm and weighs 310 g without the AC cord. Safety approvals include UL/cUL (60950-1, 62368-1), PSE, LPS, and UKCA, with EMI/EMC compliance to FCC Part 15B Class B and CE.
