NOTE

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 regula-

tion.

3. Derating may be needed under low input voltages. Please check the

derating curve for more details.

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

passes EMC directives

All specifications are typical at nominal input, full load, and 25°C unless other-

wise noted
