NOTES
1. Ripple & noise is measured at 20MHz bandwidth by using a 12" twisted pair-wire terminated with 0.1µF and 47µF
capacitors in parallel.
2. The SPS is considered a component which will be installed into final equipment. The final equipment must be
re-confirmed that it still meets EMC directives.
