Notes: 1. All parameters are specified at 230VAC input, rated load, 25°C 70% 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, other outputs at 60% rated load

6. Each output provides up to maximum current, but total load can not exceed max. output power
