  1. All parameters are measured at 230VAC input, rated load and 25°C of ambient temperature.
  2. Line regulation is measured from low line to high line at rated load.
  3. Load regulation is measured from 0% to 100% of rated load for single output models. For multi-output models, it is measured from 20% to 100% of rated load, and other output at 60% rated load.
  4. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1µF & 47µF parallel capacitor.
  5. The power supply is regarded as a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
