NOTES
1. All parameters are specified at 230VAC input, rated load, 25°C ambient.
2. Tolerances include set up tolerance, line regulation, load regulation.
3. Line regulation is measured from low line to high line at rated load.
4. Mounting holes M1 and M2 should be grounded for EMI purposes.
5. Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1uF & 47uF capacitor.
