The SMI18-5-V-P5R is an AC/DC wall mount adapter manufactured by CUI Inc. It accepts a universal input voltage range of 90 to 264 Vac at 47 to 63 Hz and provides a regulated 5 Vdc output at up to 3 A, yielding a maximum output power of 15 W. The adapter exhibits an average efficiency of 82.2% and a no load power consumption of only 0.07 W typical, meeting energy efficiency requirements.
Electrical characteristics include a ripple and noise of 100 mVp-p maximum at full load, input current of 0.48 A typical at 100 Vac, and inrush current of 50 A at 100 Vac and 60 A at 230 Vac. The adapter is designed for wall mount installation and features a compact form factor.
The adapter is suitable for powering a wide range of low-power devices such as IoT equipment, industrial controls, and consumer electronics requiring a 5V supply. Its wall mount design saves bench space and eliminates the need for a separate power cord.
The input voltage range is 90 to 264 Vac.
The output voltage is 5 Vdc and the maximum output current is 3.0 A.
The maximum output power is 15.0 W.
The average efficiency is 82.2% measured at 25%, 50%, 75%, and 100% load.
The ripple and noise is 100 mVp-p maximum at full load, nominal AC input, 25°C, with specified output termination.
The inrush current is 50 A maximum at 100 Vac and 60 A maximum at 230 Vac, at full load, 25°C, cold start.
The typical no-load power consumption at 230 Vac is 0.07 W, with a maximum of 0.075 W.
