  • All parameters are specified at 115VAC input, rated load, 25 70% RH ambient.
  • Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1 f & 47 f capacitor.
  • DC voltage: The output voltage set at point measure by plug terminal & 50% load.
  • Tolerance: includes set up tolerance, line regulation, load regulation.
  • Line regulation is measured from low line to high line at rated load.
  • Load regulation is measured from 10% to 100% rated load.
  • Derating may be needed under low input voltage. Please check the derating curve for more details.
  • The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.
