1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.

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

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

4. De-rating may apply in low input voltage. Please check the de-rating curve for more details.

5. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still

meets EMC directives.

6. Conduct this test without enclosure.

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 is taken for longer that the allowed duration indicated by curve B, the output current will drop to a constant limited current of 105% of nominal, then.

The unit between peak currents (T-

NORMAL

) is dependant up on 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.
