Note
1. All parameters NOT specially mentioned are measured at **0VAC , rated load and *5º C of ambient temperature.
2. Ripple & noise are measured at *0MHz of bandwidth by using a *2" twisted pair-wire terminated with a 0.1μ &*7μ Parallel capacitor.
3. Tolerance: Includes set up tolerance, line regulation and load regulation
4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
