We put forth a range of constant voltage transformers that are highly efficient. In these transformers, there are no semi conductors or moving parts that makes them highly reliable. These transformers have short term over load capability and higher input voltage control range for loads less than rated load. Precision made, these transformers come with very high line rejections capability and excellent input to output isolation characteristics. The other features includes intrinsic current limiting short circuit protection, output voltage corrections within ½ cle (10 m secs ) from no load to full load for specified load and line variation, energy shortage for line loss up to 3(m secs ) at typical loads. more...

We offer world class CVT in which the AC mains powers the input winding, which in turn is widely separated physically from the isolated output winding. Very moderate flux linkage levels are maintained in input winding running. The output winding has an intrinsic energy storage characteristic. This energy storage operates in conjunction with mains capacitor to produce self-generated AC flux field with is indirectly excited from the input winding.
* Rating: 75VA to 10.0KVA
Salient Features
» No use of any semiconductor or moving part offering very high reliability.
» No use of feed back control.
» Limiting of Intense current and protection short ciruit
» Energy storage for line lose up to main 3ms at typical load.
» Short term over load capacity.
» Higher input voltage control range for load less than rated low.

Ultra Isolation Transformers has been generally observed that after installing the AVC those customers who have installed the sophisticated machinery/computerized system are still facing some problem in failure of the electronic cards. The problems might be occurring due to on / off switching of inductive , capacitive ,resistive load & electronic ballasts with PWM switching system the incoming supply line are superimposed with dangerous Surge / Spike with RFI noise & harmonics. /these Surges /Spikes occurring power supply for very short duration which leads to the shortening of components life & failure rate of electronic circuits or sophisticated machines & leading to heavy loses of production. It is therefore suggested to install JINDAL”S make Isolation Transformers with Automatic Voltage Controller & at present we are manufacturing Isolation Transformers from 10KVA to 1000KVA.

CVT uses the principle of Ferro-resonance in which output winding is resonated with the help of select value of high stability capacitors. This resonating circuit gives rise to saturation of the core which prevents variation in the output against changes in the input voltage. Can be used for any application requiring a stable output voltage combined with a high degree of isolation from line disturbances.

GSA Constant Voltage Transformer (CVT) work on Ferro Resonant Principle. Units have built in harmonic filter to provide a sine wave output. Beacuse the high isolation between Input & output CVT provides protection against transient spikes an harmonics and also there is no-shock problem in case of leakage in the equipment being run on Constant Voltage Transformer (CVT).
Features of Constant Voltage Transformer:
• Output highly isolated from input
• Protected against over-load and short circuit
• Instantaneous correction
• No-moving parts, relays or electronics circuitary
