Automatic Voltage Stabilizers
We are leading Supplier and Manufacturer of Automatic voltage transformer 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
Oil Cooled Servo Voltage Stabilizer
We Leading Supplier and Manufacture of Oil Cooled Servo Stabilizers are used to protect any critical equipment, which are effected by the fluctuation in the input supply and those equipments do not operate when they are not used at the specified voltage. Our Servo Stabilizers by providing constant output with tolerance of +/-1% makes equipments operate efficiently and hence improve their life. Also protect from being damaged due to high and low voltage.
