Ultra Isolation Transformer By Shepherd Transformer Industries

We are engaged in manufacturing, exporting and supplying excellent quality Ultra Isolation Transformer to our valuable clients. An isolation transformer, which often has symmetrical windings, 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 can be used to block transmission of DC signals from one circuit to the other, but allow AC signals to pass. They will also block interference caused by ground loops. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment such as computers or laboratory instruments.

Shielded Isolation Transformers :
Shielded isolation transformers have all the features of the standard isolation transformers plus they also incorporate a full metallic shielding (this shielding is often copper or aluminum) between the primary and secondary windings. These shielded isolation transformers are then referred to as electrostaticly shielded isolation transformers. The electrostatic shield ( "Faraday Shield" ) is connected to earth ground and performs two functions :
It filters (attenuates) voltage spikes (voltage transients). These shielded isolation transformers have an attenuation ratio of 100 to 1.
It filters common mode noise. This is usually an attenuation of approximately 30 decibels.
