Isolation Transformer

An ordinary isolation transformer isolates one circuit from another. Such a transformer is adequate for use with low gain circuits or insensitive instruments. However, if the transformers must work into a high gain load or sensitive instrumentation, noise potentials between the primary circuit and ground must be prevented from affecting the secondary circuits due to capacitive and resistive coupling between the transformers windings.

 

VERTEX Ultra Isolation Transformer (UIT) employs a unique multiple shielding technique that reduces the interwinding capacitance to a large extent and increases the DC isolation.
