Notes:1. All parameters NOT specially mentinoed are measured at 230VAC input, rated load and 25℃of ambient temperature.
2.Ripple and noise are measured at 20MHz bandwidth by using a 12” twisted pair-wire terminated with a 0.1μF and a 47 μF parallel capacitor.
3.Accuracy: including preset errors, linear adjustment rate and load adjustment rate.
4.Linear adjustment: taken under rated load from low voltage to high voltage.
5.Load adjustment: taken under 0~100% of rated load.
6. The power supply is taken as part of the whole system, and needs to be confirmed with final equipment for EMC.
