Notes
|
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: high load conditions change in the rated input voltage from low to measured;
5. Load regulation: the measured output load from 20% to 100% load change measured, other load is fixed at 60% load.
