Drive isolation transformer is not a shielded isolation transformer, but act to lessen transient generation into the supply power and allow for high surge, harmonic and offset currents. It is designed for the requirements of both adjustable frequency and dc motor drive power isolation. This transformer was made for the mechanical stress of dc drive current spikes, as well as the thermal and mechanical stress of highly cyclic process control applications.
