Constant Voltage Transformer :
In our Ferro Resonant type Constant Voltage Transformers - CVT, the AC mains power the input winding, which is widely separated physically from the isolated output winding. The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operate in conjunction with mains capacitor to produce self-generated AC flux Field which is indirectly extracted from the Input Winding.
These Constant Voltage transformer or CVT use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output with a varying input. The ferroresonant approach is attractive due to its lack of active components, relying on the square loop saturation characteristics of the tank circuit to absorb variations in average input voltage.
The ferroresonant action is a flux limiter rather than a voltage regulator, but with a fixed supply frequency it can maintain an almost constant average output voltage even as the input voltage varies widely.
All problems related to variation / fluctuation in Voltages are effectively handled because of this principle and a constant voltage output of ± 1% is given.
The ferroresonant transformers, which are also known as Constant Voltage Transformers (CVTs) or ferros, are also good surge suppressors, as they provide high isolation and inherent short-circuit protection.
We are a renowned manufacturer of Constant Voltage Transformer and The Result of Constant Voltage Transformer - CVT are as under:

Why CVT ?
We manufacture Constant Voltage Regulators which use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output with a varying input. The constant voltage regulator approach is attractive due to its lack of active components, relying on the square loop saturation characteristics of the tank circuit to absorb variations in average input voltage.
Electronics instruments, Machines, Computers and other microprocessor based equipment are designed to operate on steady stream sine wave of 220/230 V RMS. The nature of utility power is such that very frequently the equipment encounter electrical disturbances and voltages which are beyond the range of those equipment. The quality of power has deteriorated so much during the past several years that today it is impossible to work without encountering disturbances. Equipment using microprocessors are especially vulnerable due to the degradation of the utility power.
Thus in order to reach the equipment potentially damaging impulses generated outside your location travel through the impedances of lot of copper wire. Although this barrier serves to dampen out many of these disturbances the real problem occurs along the electrical path from the point the power enters your premises to your equipment. Between these points are all kinds of devices such as lifts, air conditioners, Fluorescent tube chokes, Photo copiers and in case of factories the machines. Any equipment that arcs, cycle on off, or draws excessive bursts of current becomes the cause of potential hazard to your micro processor based equipment.
