Constant Voltage Transformers

CVT (Constant Voltage Transformer) is designed on the basic principle of Ferro - resonance, in which output winding is resonated with the help of select value or high stability capacitors. This is the most reliable product as there is no moving part thus bringing maintenance cost to zero. We are looking for inquiries from South India region including Andhra Pradesh, Karnataka, Kerala and Tamil Nadu and cities like Bangalore, Chennai, and Hyderabad.

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 are 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.
