Product Description
Electric components mounted on min.V-1 PWB, Open frame power supply designed for building-in to an ITE
end-product.
Model Differences
The power supplies in the AU425SXXYWW and AU300SXXYWW are similar to each other except for output
ratings and secondary winding of power transformer.
AU425SXXYWW and AU300SXXYWW are similar to each other in construction except for the output ratings
and the additional cooling system required for AU425SXXYWW.
Each model has two constructions A and B. They are similar to each other except for limited components in
the primary and secondary circuits, which have the impact on the power supply functionality. Refer to Safety
Component List for the differences regarding the safety impact.

Special Instructions to UL Representative
Inspect the transformer(s) listed in table "Electric Strength Test Special Constructions" per AA1.1 (C). When
the tests are conducted at other location, inspect test record and specification sheet provided by the
component manufacturer. Verify the specification sheet indicates 100% routine test specified in BD1.1 is
conducted at the component manufacturer. The test record noted above shall be submitted to the
manufacturer from transformer manufacturer. The test record can be in the form of a actual test record. A
stamp or sticker on the transformer or other method verifying the routine test is being completed on 100%
production is also acceptable.
