• Add to Inquiry Basket | Automatic electric ltd. Is engaged in manufacturing electrical instruments, power systems and instrument transformers in india. The company has been accredited with an iso 9001 certification. The continuously variable voltage auto-transformer is a device for stepless, breakless & continuous control of ac voltage & therefore for various parameters, dependent on ac voltage. The following are its salient features:
1. dimmerstat is meant for operation from a nominal input voltage of 240v 1ph ac
2. gives output voltage between 0 to 240v or 0 to 270v ac
3. simple, rugged construction.
4. coils made from high grade crgo silicon steel & 99.9% pure copper.
5. output voltage variation is smooth, continuous, breakless & linearly proportional to angular rotation.
6. high efficiency.
7. negligible waveform & power factor distortion.
8. short time overload capacity is considerable
9. remote operation possible by motorization.
10. wide range of current ratings.
11. high quality carbon brush used for current collection.
Used in auditorium, hotels, conference halls, exhibitions, laboratories, ac voltage stabilizers, rectifiers, battery chargers, temperature control of ovens, furnaces, testing of instruments, relays, circuit breakers, welding, electro-plating, anodizing, colleges & universities.
