| 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. |
