Notes
|
1. All parameters are measured at 220 V AC input, rated load, ambient temperature 25 ° C, humidity 70%;
2. Accuracy: including setting error, line regulation, load regulation rate;
3. Ripple test: 30cm long wire with the power and load, load and 0.1u and 47u capacitance to 20MHz
oscilloscope measured at the load side;
4. Line regulation: the rated load conditions, the input voltage changes from low to high measured;
5. Load regulation: Measured output is measured from 0% load to 100% load change.
