Constant Voltage Transformers

Single Phase Transformers

Constant voltage single phase transformer in chennai, tamilnadu,. uses 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 ferromagnetic 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. Older designs of ferromagnetic transformers had an output with high harmonic content, leading to a distorted output waveform. Modern devices are used to construct a perfect sine wave. The ferromagnetic 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.


Salient Features:


Isolation transformer : the input supply is completely isolated from the output, by means of an isolation transformer.

 

Ferraro resonant technology:


  • No moving parts
  • Overload protection
  • Short circuit protection
  • Spike rejection capabilities
  • Floating output
  • No semi-conductors used (normal cvt)
  • No electronics circuits (normal cvt)
  • Faster voltage correction than servo stabilizer

 

Applications:


The CVT's are used for various applications like computers, data processing equipment, audio/video equipment, photo processing equipment, bio-medical equipment, telex, EPABX, fax, cash registers, electronic typewriters, internet application, modem & other accessories like netphone, control panels, etc.

Constant Voltage Transformer CVT

We are Leading Manufacturer, Supplier of Constant Voltage Transformers CVT.,

Advantages of CVT:


  •   No moving parts
  •   Overload protection
  •   Short circuit protection
  •   Spike rejection capabilities
  •   Faster voltage correction than servo stabilizers

Disadvantages of CVT:

  • Output voltage varies as a function of frequency unless a frequency compensating network is used. The output voltage will vary 1.6% for a variation of 1% (0.5 Hz) input frequency.
  • Physical size & weight of a CVT is larger than a linear transformer of the same rating.  
  • There is a hum noise increases as the CVT rating increases.
  • Very expensive when compared to Servo Stabilisers.

Recommendations:

  • Switch on CVT before switching ON the Load & while switching OFF switch, OFF Load first & then the CVT.
  • Switch OFF CVT when not in use to save power.
  • CVT cannot be used for an inductive load. 
  • Keep magnetic storage & display devices like diskettes, spools, monitors, etc. away from the CVT.
