Notes:
1. All parameters are specified at 230V I/P, rated load, 25 C, 70% RH ambient
2. Ripple and noise are measured at 20MHz using a 12” twisted pair terminated with a 0.1uF and 47uF
capacitor.
3. Line regulation is measured from low line to high line at rated load.
4. Load regulation is measured for 0% to 100% rated load.
