NOTE |
1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 "c of ambient temperature.
2.Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1 uf & 47uf parallel capacitor.
3.Tolerance : includes set up tolerance, line regulation and load regulation.
4.The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. |
