Notes for Triple Output Models

1. guaranteed by design, not tested.

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:

A. Positive aux. = 2.5 W (50%); negative aux. = 2.5 W to 0.5 W (50% to 10%).

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

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