A Transformer Variac Dimmer (Variable Autotransformer) is a precision device used to control and adjust AC voltage smoothly and continuously. It allows the user to vary the output voltage from 0 to above the input voltage without waveform distortion, making it ideal for applications requiring fine voltage control.

Built with high-quality copper windings and a durable carbon brush mechanism, the Variac Dimmer ensures stable output, high efficiency, and low heat generation. It is widely used in laboratories, workshops, industries, testing departments, and service centers for controlling power supplied to motors, lights, heaters, and electronic equipment.

A Variac Dimmer is a high-precision variable autotransformer designed to provide smooth and stepless control of AC voltage. By adjusting the rotary knob, the output voltage can be varied from 0 to 270V AC (for 230V input) or as per model specifications. This allows precise voltage regulation without distortion, making it ideal for testing, calibration, dimming, and controlled power applications.

Engineered with heavy-duty copper windings, a durable carbon brush mechanism, and low-loss construction, the Variac Dimmer ensures stable output, high efficiency, and long operational life. It is widely used in laboratories, workshops, industries, service centers, and R&D environments.

A Single Phase Variac Transformer is a high-precision variable autotransformer designed to provide smooth, stepless, and accurate control of AC voltage. By rotating the control knob, the output voltage can be varied from 0 to 270V AC (for 230V input) or as per model specifications, without causing any waveform distortion. This makes it ideal for testing, calibration, and controlled power applications.

Built with high-quality copper windings, a robust carbon brush mechanism, and a low-loss toroidal or laminated core, the Single Phase Variac offers excellent voltage regulation, stable performance, and long service life. It is widely used in laboratories, service centers, workshops, industries, and educational environments.

A Three-Phase Variac (15 Amp) is a heavy-duty variable autotransformer designed to provide smooth, adjustable AC voltage for three-phase electrical systems. It allows precise control of output voltage from 0 to above line voltage (typically up to 480 V or 520 V depending on design) without waveform distortion. This makes it ideal for laboratory, industrial, and testing environments where stable, adjustable three-phase power is required

A Three Phase Variable Transformer is a robust and precision-engineered variable autotransformer designed to provide smooth, stepless, and accurate control of AC voltage across all three phases. It allows the output voltage to be varied from 0 to 470V AC (for 415V input) or as per model specifications, ensuring uniform voltage adjustment without waveform distortion.

Built with heavy-duty copper windings, durable carbon brushes, and a low-loss toroidal/laminated core, the Three Phase Variac delivers high efficiency, stable output, and long operational life. It is ideal for industrial applications requiring controlled three-phase power such as motor testing, equipment calibration, R&D experiments, and voltage regulation setups.
