NOTES
1. All parameters not specially mentioned are measured at 230VAC input, rated load, and 25C ambient temperature. 2. Ripple & noise are measured at 20MHz using a 12" twisted pair-wire terminated with 0.1uF & 47uF capacitors in parallel. 3. Tolerance: includes set up tolerance, line regulation, and load regulation. 4. The power supply is considered a component, which will be installed into final equipment. The final equipment must be reconfirmed that it still meets EMC directives. 5. Mounting holes M1 and M2 should be grounded for EMI purposes.
