NOTES
1. Ripple & noise is measured at 20MHz bandwidth by using 12" twisted pair-wire terminated with 0.1µF and 47µF
capacitors in parallel.
2. Tolerance includes set up tolerance, line regulation, and load regulation.
3. The length of the setup time is measured a first cold start. Turning the power supply ON and OFF very quickly may lead
to an increase in the setup time.
4. 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.
