Dimmerstat® Continuosly Variable Voltage Auto-Transformer
Dimmerstat' is registered trade mark for AE make continuously variable voltage auto-transformer. It is the most effective device for stepless, breakless & continuous control of AC voltage & therefore for various parameters, dependent on AC voltage.
APPLICATIONS
• AC Voltage Stabilizers, Rectifiers, Battery Chargers.
• Temperature control of Ovens, Furnaces.
• Testing of Instruments, Relays, Circuit Breakers etc.
• Welding, Electro-plating, Anodizing etc.
• Colleges & Universities.
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.
FEATURES :
• Simple, rugged construction.
• Coils made from high grade CRGO Silicon Steel & 99.9% pure copper.
• Output voltage variation is smooth, continuous, breakless & linearly proportional to angular rotation.
• High efficiency.
• Negligible waveform & power factor distortion.
• Excellent short time overload capacity.
• Remote operation possible by motorization.
• Wide range of current ratings.
• High quality carbon brush used for current collection
