Issue:
Taps provided on Transformers may be adjusted to provide for different Primary input voltages.

Product Line:
LV Transformers

Environment:
Applies to all Transformers with taps supplied by SquareD/Schneider Electric

Cause:
Supply voltages for Transformer Primaries can vary up or down from optimum or rated voltage

Resolution:
Taps are provided on the designed Primary of the Transformer, usually located on the face of the coils of a Ventilated unit. The purpose of a tap is to provide the customer with connection points on the Primary coil so as to compensate for poor incoming/source voltage. Poor voltage is anything other than nominal and could be high or low. By utilizing a tap, it is possible for the customer to get an output from the Transformer that is close to it's designed value. To intentionally over or under excite a Transformer by putting a significantly higher or lower voltage on a tap than it is rated can have a potentially catastrophic affect on the Transformer and is not supported by Square D/Schneider Electric.
