An isolation transformer is a transformer, often with symmetrical windings, which is used to decouple two circuits. An isolation transformer allows an AC signal or power to be taken from one device and fed into another without electrically connecting the two circuits. Isolation transformers block transmission of DC signals from one circuit to the other, but allow AC signals to pass. They also block interference caused by ground loops. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment such as computers, Lab Instruments, CNC Machines, Medical Equipments, etc.
VERTEX Isolation Transformer employs a unique multiple shielding technique that reduces the interwinding capacitance to a large extent and increases the DC isolation.
