| Note | 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4.Line regulation is measured from low line to high line at rated load. 5.Load regulation is measured from 0% to 100% rated load 6.The ambient temperature derating of 5℃/1000 m is needed for operating altitude greater than 2000m(6500ft) 7.The power supply is considered as a component which will be installed into a final equipment.The final equipment must be re-confirmed that it still meets EMC directives. |
