Notes

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

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

3. 33% Duty cycle max within every 30S. Average output power should not exceed the rated power.

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