  NOTE	1. All paramenter Not specially mentioned are measureed at 230vac input, rated load and  25℃ of ambient temperature,
  	2. Ripple & noise are measureed:Connect 0.1uf & 47uf capacitorat in parallel at the terminal, and measure under 20MHz of bandwidth.
  	3. Eusurethat the power supply is used under the rated parameters and enviroment

1.All parameters NOT specially mentioned are measured at 220VAC input, rated load and 25C of ambient temperature.
2.Ripple & noise are measured at 20MHz of bandwidth by using a12'' twisted pair-wire terminated with a 0.1uf 10uf parallel capacitor
3.Tolerance: includes set up tolerance, line regulation and load regulation.
