Note

1.All parameters NOT specially mentioned are measured at 230V AC input,rated load and 25°C ambient temperature.

2.Ripple &Noise are measured at 20MHZ bandwidth oscilloscope and with 0.1uf &47uf parallel capacitor.

3.The power supply is considered a component which will be installed a final equipment.The final equipment must be re- confirmed that it still meets EMC directives.
