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. Output provided up to maximum current, but related to maximum output power
6. Each output provide up to maximum current, but total load cannot exceed max. output power
7. Mounting holes M1 and M2 should be grounded for purposes
