1. Ripple & noise is measured at 20MHz limited bandwidth and using a 12" twisted pair-wire terminated with a 0.1µF & 47µF capacitors in parallel.  
2. For voltages near the low end of the input voltage range, see the derating curve for the power supply output rating.  
3. The 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.
