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 bandwidth by using a 12" twisted pair-wire terminated with a 0.1uF & 47uF parallel capacitor.

3. Tolerances include 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. Derating may be needed under low input voltages. Please check the derating curve for more details.
