Auto Variable Transformer
Auto Variable Transformer
Udeyraj Electricals Private Limited offers Auto Variable Transformer. Reguvolt is now available in high current ranges from 255 Amps. up to 1000 Amps, in both single phase & three phase model. Special paralleling techniques designed by us, have made it possible to surpass pervious current limit of 200 Amps. in torrodial auto transformers.
Product & Technology News
- Single phase:
- Input: 240V, 50/60Hz AC 1 ph. Output: 0-270V, 50/60Hz AC 1 ph.
- Three phase:
- Input: 415V, 50/60Hz AC 3 ph. Output: 0-470V, 50/60Hz AC 3 ph
- Excellent Regulation: The drop in voltage from “no load to full load” is minimal in Reguvolt Auto-transformers.
- High Efficiency: Careful design and proper selection of copper and core assures the user of low watt loss, as compared to other type of controllers.
- No Wave From Distortion: Reguvolt provides an output voltage wave-form, which is a faithful and distortion less replica of the input voltage wave form.
- Silver Plated Communator: A special silver plating technique is used on the commutator, enabling it to with stand high overloads & maintain constant contact drop. It is also ensures smooth operation, long life & increased resistance to corrosion.
- Smooth & Linear Output: As voltage between turns is small and as the brush-arm is in constant contact with more then one turn, harmful sparking is avoided and output voltage can be set very easily to fraction of a volt from zero onwards by rotation of the knob.
- Low Magnetizing Current: By using an adequate section of high quality grain oriented silicon steel, the iron losses in Reguvolt, are controlled to the minimum. The no-load current in all Reguvolt transformers, is invariably less than 3% of the rated current.
