Note
|
1. All parameters 220V AC 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, other load fixed at 60% of the load;
6.And natural ventilation can only use 70% of the maximum load; 25cfm forced air cooling, can be used 100% load. Ver:1.1
