Ripple & noise is measured at 20MHz limited bandwidth and using a 12" twisted pair-wire terminated with a 0.1µF & 47µF capacitors in parallel. 2. For voltages near the low end of the input voltage range, see the derating curve for the power supply output rating. 3. The power supply is considered a component which will be installed into final equipment. The final equipment must be re-confirmed that it still meets EMC directives.

PEAK LOADING I T-peak T-peak represents the period during which the output current is at 110% to 150% of nominal (shown as I-peak). Curve B shows the relationship between the percentage of peak current (I-peak) and the allowable duration (T-peak). If the peak current takes longer than the allowed duration indicated by curve B, the output current will drop to a constant limited current of 105% of nominal. The unit between peak currents (T-normal) is dependant upon the output current drawn between the peaks (I-normal) and curve A shows the relationship between the two. The higher the percentage of normal current (I-normal) is of the nominal current, the longer the interval (T-normal) before the next peak current can be drawn.
