The transformers we make available are manufactured in compliance with international quality standards. Bulk orders of these are processed by us as per the specific requirements of the buyers. The entire range of the Voltage Transformer is reasonably priced by us.   Details : Constant Voltage Transformer as the name tell itself that CVT provides constant voltage despite of specified voltage fluctuation at the input.The AC mains powers up the input winding which is physically as well as galvanically isolated from secondary or output winding The input winding runs at moderate flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operates in conjunction with mains capacitor to produce self-generated AC flux field which is indirectly excited from the input winding. The result is instantaneous voltage regulation. No transient and spikes. Sinewave output. A perfect answer and remedy for every electronic equipment.   Salient Features :       No semiconductors or moving parts used, hence very high reliability No feedback control used Intrinsic current limiting and short circuit protection Output voltage correction within ½ Cycle ( 10 ms) from no load to full load for specified load and line variation Short term over load capability Energy storage for line loss up to 3 ms at typical loads Higher input voltage control range, for loads less than rated load Very high line transient/spike rejection capability and excellent input to output isolation characteristics Output floating (optional)      Appplications : Computers, Data Processing equipment, Colour Photography Labs., Bio-medical equipment, PA equipment, Telecommunication, TV, VCD/DVD recorders & players, Teleprinters, Fax machines and all other sensitive electronic devices.Precautions while using CVT : Keep magnetic storage and display devices like Diskettes, Spools, Monitors etc. away from the CVT Switch on the CVT before switching ON the attached peripherals and while switching off, switch OFF attached peripherals first and then the CVT Avoid using the CVT for high inductive loads. Check frequency before using the CVT with a generator. Recommended frequency: 50± 1Hz Switch OFF the CVT when not in use.

TThe CVT uses the unique principle of ferroresonance: operation of a transformer in the region of magnetic saturation. When the iron core of a transformer is in saturation, relatively large changes in winding current results in very small changes in magnetic flux. Winding current and magnetic flux are proportional to the input and output voltage, respectively. This means that relatively large changes in input voltage result in small changes in output voltage: this being the fundamental purpose of an automatic voltage regulator. 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. Dishant Electronics makes wide range of CVT including various features at very competitive rate.   FEATURE Proven technology High reliability Fast response Output short circuit protected Rugged industrial design High efficiency products and very low electricity consumption as compared to local CVT Affordable price   APPLICATION Embroidery machinesSignaling instrumentsEpabx systemsElectronic typewritersComputers & peripheralsTransmittersScientific intrumentsLaboratory equipmentsPhoto flash equipments

• Out Put Voltage: 220 V / 230 V +/ - 1%

Our range of CVT (constant voltage transformer) operates at a relatively constant frequency providing substantial constant output voltage in spite of large changes in the input voltage. This power equipment comprises a high resistance transformer, which has an air gap in a magnetic shut for providing a constant voltage output. Resonant action of the secondary winding of the transformer and the capacitor is responsible for the whole action.

• Input Voltage: 180V-260V (other choices on request)

The AC mains powers 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 storage characteristic and this energy storage operates in conjunction with mains capacitor to produce self-generated AC flux field which is indirectly excited form the input winding.Switch on the CVT before switching ON the attached peripherals and while switching off, switch OFF attached peripherals first and then the CVT.

Constant Voltage Transformers (CVTs) are AC Voltage Stabilizers providing steady voltage to electrical equipment/instruments and protecting them from the harmful effects of under-voltage and over-voltage. SAPT Ferro-resonant CVTs are the ideal maintenance free solutions for loads that can suffer erratic operation or be damaged by electrical noise (common and series mode) local transients, mains power sags, surges and brownouts. It is maintenance free because of no moving part & fast correction speed compare to servo voltage stabilizer.

Constant Voltage Transformer ( CVT ) 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 reason we use a CVT and not a voltage stabilizer for computer applications is that in the voltage stabilizer relays are present and when these relays operate (switch), the output voltage may be interrupted for a short time. Such a transient may not be desirable for computers which may cause the computer to reboot. Also, the CVT provides a clean spike-free output voltage. The voltage regulation possible in a CVT also is good.
