12V 1A EU model switching power adapter
Input: 100-230V 50/60Hz
Output: 12V 1A

 Ripple & Noise are tested by dc loading side parallel with a 47uF/EC and 0.1uF/Ceramic Capacitors and measured Band-Width with DC-20MHz and the result must less than 150mV.

The average efficiency is lager than 77.85% which is at 115Vac/60Hz and 230Vac/50Hz with 100%, 75%, 50% and 25% rated load. This result compy with the efficiency level V of Erp.

The line regulation of rated output voltage is less than +/-5%, while measuring at rated load and +/-10% of input voltage changing.

the load regulation of rated output voltage is less than +/-5%, at measured output load from 10% to 100% rated load.

At nominal input AC voltage and full load, the turn on delay time must less than 3000mS.

The supply have a start-up rise time of less than 30mS within regulation limits for all DC outputs.

At nominal input AC voltage and full load, the hold up time must larger than 10mS.

Protecion Characteristics:
Over current protection;
Over voltage protection;
