NOTES
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. 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.
3. This product is Listed to applicable standards and requirements by UL.
*Due to advances in technology, specifications subject to change without notice.
