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
