    We are one of trusted Manufacturers, Suppliers and Exporters of Isolation Transformer. We offer a range of Isolation Transformer that is mostly used for electric power transfer from an alternating current (AC) source electrical device. Isolation Transformer assists in shifting the power from one signal to other without connecting the two circuits electrically. The perfect role of our range of isolation transformer is to use as power transformer with safety precaution. It provides protection against high voltage surges, spikes and electrical noises. Isolation transformers are double copper wounded transformer and provide very high resistance and extremely low capacitance between windings preventing the passage offline voltage, transients, spike, leakage to the secondary, which in turn is connected to sensitive equipment. It specially prevents the line voltage disturbances from reaching the typical load equipment, thus saving enormous down time, production losses, damages, and accidents. The Isolation Transformers employs special shielding, super enameled copper winding and better insulating material. These minimizes common mode noise, provides precise load regulation, high insulation and continuous reliable operation at full rated load up to 50°c. Adequate isolation between a power source and a user of electronic equipment ensures the safety of that equipment. Given the high voltages that exist in modern electronic equipment, proper isolation protects an operator from contact with excessive electrical energy should a short circuit occur in the equipment. Isolation transformers have represented a traditional solution for providing high isolation in electronic circuitry. Even with the increased use of efficient, switched-mode power supplies (SMPS), isolation transformers can improve the overall isolation of an electronic design without severe penalties in added size, weight, and cost. Isolation transformers offer an effective means of meeting the requirements of domestic and international safety standards for electronic equipment. Isolation transformers enable a variety of electronic systems to meet safety requirements. Such systems include medical diagnostic equipment, computer systems, and telecommunications equipment. The systems may incorporate linear power supplies, SMPS, and sometimes a combination of both. A single isolation transformer can help an electronic design meet all of its isolation requirements. With proper system design, an isolation transformer can also help reduce the size and cost of the power-electronics components. Technical Specification : Rating Available : 1Kva to 1000kva Single Phase and 3 phase/Air and Oil Cooled. Input Voltage -400V AC(Phase to Phase) Frequency : 50 Hz Transformation Ratio : 1:1 Duty cycle : Continuous Highlights : Longer service Low operating cost Low maintenance Incorporated with advanced technology Special Features : Isolation transformers can be used to protect people against the dangers of electric shocks. Isolation transformers can 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 medical equipment, computers or precision laboratory measuring instruments.

    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 circuits 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 is designed as per the international standards which give 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.
