Notes

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

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

3. 33.3% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.

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