Continuously Variable Voltage Auto Transformer
Continuously Variable Voltage Auto Transformer is manufactured by Techno System. It is the most useful and effective device for step-less, breakless, and continuous control of AC Voltage and, therefore, for control of various other parameters, dependent on AC Voltage. This widely known and highly acclaimed product is an ideal controlling device for numerous applications in laboratories and industrial and commercial fields.
The basic. Continuously Variable Voltage Auto Transformer is meant for operation of a nominal voltage of 240V AC and can give output voltage anywhere between 0 to 240V, or up to 270V by simple transformer action. Three such Continuously Variable Voltage Auto Transformers when connected to an electrical and mechanical in tandem, become suitable for operation off 415V 3 Phase AC supply and to give output from 0 to 415V, or up to 470V.
Optional Feature
Spectron Continuously Variable Voltage Auto Transformer is probably the best device to obtain a continuously variable output voltage from a fixed AC Voltage source. This is evident from various special features and operating advantages, given below:
- Simple & rugged in construction – therefore has a long life, is relatively cheaper, noiseless in operation, compact, and easy to understand, maintain, and repair.
- Good regulation- Voltage drop on load is low, due to the low resistance of the conductor and low leakage flux of the toroidal core.
- Output voltage variation on no-load and even on load is effortless, smooth, continuous, breakless, and linearly proportional to angular rotation.
- High Efficiency – No-load losses and load losses are low.
- Negligible waveform and power factor distortion due to simple transformer action.
- Excellent short-time overload capacity.
- Easy for remote operation with the help of a motor drive.
- Wide range of models.
