notes

1. Guaranteed by design and/or analysis. not an in-line test.

2. The sum of the 12 volt auxiliary output currents may not exceed 416 mA.

3. The sum of the auxiliary output power may not exceed 5 watts. up to 80% of the

total power (5W) is available from either auxiliary providing the opposite auxiliary

is carrying 20% of the total auxiliary power used.

4. Load regulation for the +5 is specified at 0.0 to 2.0 A with the aux. both held at 2.5

W (208 mA). Load regulation for the auxiliary is specified as both auxiliaries from

0.0 to 2.5 W (208 mA) at the same time with the +5 held at 2.0 A.

5. Cross regulation occurs between the two auxiliaries and is measured on –aux. +5

is held constant at 2.0 A. Cross regulation is specified for two conditions:

5.A.Positiveaux.=2.5W(50%);negativeaux.=2.5Wto0.5W(50%to10%).

5.B.From+Po=70%and-Po=30%to+Po=30%and-Po=70%.

Above conditions are referenced to 50%/50% balanced loads.

value.

9. At inputs above 40 volts with temperatures above approximately 100°C, to ensure

start-up, transition time should be greater than 5 ms and use of the inhibit function

should be avoided.

10. Applicable to each output. no effect on dc performance.
