Isolation Transformer
Transformers also provide an extremely useful feature called isolation, which is the ability to couple one circuit to another without the use of direct wire connections. There are applications where electrical isolation is needed between two AC circuit without any transformation of voltage or current levels. In these instances, transformers called isolation transformers having 1:1 transformation ratios are used.
Our Isolation Transformers isolate the equipments from noisy power line hence providing a better option to clients. These remove power line noise, surges, spikes and transients. It also provides high insulation resistance and provides complete electromagnetic and electrostatic shielding.
Our range of Isolation Transformers are designed as per the guidelines of ISO 2026 which gives an assurance to the customer on the high quality of the product. An isolation transformer does not have a direct electrical path from the power input side to the power output side. The term is also used to define how much electrical isolation exists between the input and output windings. For example when using line-voltage input transformers to power low voltage device handled by humans, a high degree of isolation is required for safety. Isolated transformers often use separate bobbins for the primary and secondary coil windings, but usually the windings are just wound on top of each other with insulation in between. There is usually an electrostatic shield between windings which is tied to transformer case.
