1 DC voltage: The output voltage set at point measure by plug terminal & 50% load.
2 Ripple & noise are measured at 20 MHz by using a 12" twisted pair terminated with a 0.1µF & 47µF capacitor.
3 Tolerance: includes set up tolerance, line regulation, load regulation.
4 Line regulation is measured from low line to high line at rated load.
5 Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
6 Maximum input voltage is 305 VAC.
