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.
