All parameters are specified at 230VAC input, rated load, 25C RH ambient 2. Tolerance includes set up tolerance, line regulation, load regulation 3. Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1uF & 47 uF capacitor 4. Line regulation is measured from low line to high line at rated load 5. Load regulation is measured from 20% to 100% rated load, and other output at 60% rated load 6. Each output provides up to maximum current, but total load can not exceed maximum output power 7.
