Dimmerstat ® Continuously Variable Voltage Auto-Transformer
Dimmerstat® is registered trade mark for AE and make continuously variable voltage auto-transformers. It is the most effective device for stepless, breakless & continuous control of AC voltage & therefore for various parameters, dependent on AC voltage.
The basic Dimmerstat is meant for operation from a nominal input voltage of 240V 1ph AC & can give output voltage anywhere between 0 to 240V or 0 to 270V AC by simple transformer action. Three such Dimmerstats connected electrically in star and mechanically in tandem, become suitable for operation from a nominal input voltage of 415V 3Ph AC and can give output anywhere between 0 to 415V or 0 to 470V.s
