Note:

1. All parameters NOT specially mentioned are measured at230V/50HZ AC input, rated load and 25°C ambient temperature.   2. Ripple & Noise are measured at 20MHZ bandwidth oscilloscope and with0.1uf & 47uf parallel capacitorat 100% duty output 3. Voltage Tolerance: includes line regulation, load regulation and set-up tolerance.

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