A control system and method of controlling an uninterruptible power supply (UPS) system prevents a load anomaly such as transformer DC offset, resulting from a supply disruption such as a voltage sag, by modifying the UPS supplied power curve. The UPS supplied power curve maintains a predetermined power for a predetermined duration to cause the UPS supplied power curve to depart from normal supply curve post sag detection. Following the predetermined duration the UPS supplied power curve is conformed to the normal power supply curve until restoration of the source power supply or engagement of a secondary power source.
