PACKING

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25

℃

of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation and load regulation.

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

EMC directives.

5. The over temperature protection (OTP) is the built-in function of the control IC (U1). The activating level described above is based on the specification

provided by the IC manufacturer.

Touch current was measured from primary input to DC output

7. The ambient temperature derating of 3.5

℃

/1000m with fanless models and of 5

℃

/1000m with fan models for operating altitude higher than 2000m(6500ft).
