Issue:
Use of Transformers with UPS systems

Product Line:
LV Transformers

Environment:
Applies to Low Voltage Transformers by SquareD/Schneider Electric

Cause:
Output voltages of UPS systems may require changing to a more suitable level

Resolution:

SquareD/Schneider Electric does not recommend that standard Transformers be connected to the output of UPS systems, or at the load side of adjustable frequency motor drives. Standard Transformers are designed for a maximum of 5% total harmonic voltage distortion on the input, and the output voltage of many UPS systems and drives will exceed that maximum. For further information contact your Distributor or local SquareD/Schneider Electric Sales Office.
