Notes

1. All paramterers NOT specially mentioned are measure at 230VAC input, rated load and 25°C of ambient temperature.

2. Ripple and noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uf and 47uf parallell 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.

All specifications are typical at nominal input, full load, and 25°C unless otherwise noted
