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 0.1µ &47µ 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. |
