Note

1. All parameters NOT specially mentioned are measured at 220VAC input, rated load and 25°C of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 10uf parallel capacitor.

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

4. Derating may be needed under low input voltages.
