Notes

1. All parameters 230VAC input, rated load, ambient temperature 25 ℃, measured under conditions of 70% humidity;

2. Accuracy: includes set up tolerance, line regulation, load regulation and so on;

3. Ripple Test: 30cm long strands connect the power supply and the load on the load side and 0.1u and 47u capacitor to 20MHz oscilloscope measured at the load end;

4. Line regulation: at rated load conditions, the input voltage changes from low to high measured;

5. Load regulation: the measured output load from 0 to 100% load change measured;
