NOTES
1. All parameters NOT specially mentioned are measured at 230VAC input, rated load, and 25C ambient temperature. 2. Ripple & noise are measured at 20MHz bandwidth by using a 12" twisted pair-wire terminated with a 0.1uF& 47uF parallel capacitor. 3. Tolerances include set up tolerance, line regulation, and load regulation. 4. This power supply is considered a component which will be installed into final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
