NOTES

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

2. Ripple & noise are measured at 20MHz using a 12" twisted pair-wire terminated with 0.1uF & 47uF capacitors in parallel.

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

4. The power supply is considered a component, which will be installed into final equipment. The final equipment must be re-

confirmed that it still meets EMC directives.

5. Mounting holes M1 and M2 should be grounded for EMI purposes.
