1.All parameters are specified at normal input(F:24Vdc, G:48Vdc), rated load, 25 70% RH ambient. ℃

2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1 f & 47 f capacitor. μμ

3.Line regulation is measured from low line to high line at rated load.

4.Load regulation is measured from 0% to 100% rated load.

5.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please
refer to EMI testing of component power supplies.(as available on http://www.meanwell.com)

External Output Trimming

In order to trim the voltage up or down one needs to connect the trim resistor either between the trim pin and -Vo for trim-up and between trim pin and
+Vo for trim-down.The output voltage trim range is 10%. This is shown in Figures 1 and 2:±
