1.All parameters 230V AC input, rated load, ambient temperature 25 ℃, measured under conditions of 70% humidity;
2. Accuracy: includes set up tolerance, line regulation, load regulation, etc;
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 change from low to high measured;
5.Load regulation:the measured output from 0-100% load changes measured;

6.The load is more than 150W, need to add at least 10CFM to heat dissipation.
