note

1. All the parameters in has not specified, all is in 230 VAC voltage input, rated load and 25 ℃ conditions measuring income value.
2. Ripple and noise voltage is in 20 MHz bandwidth oscilloscope take 12 inches twisted pair end with 0.1 mu and 47 u when capacitance measurement.
3. Tolerance is voltage setting error, the voltage adjustment rate and adjust the sum total of the current rate.
4. The power to consider as a device installed in final equipment, this equipment must be to make sure it’s EMC index.
5. Specific output current see output drop forehead curve.
