  Variable Auto Transformer will be having round Toroidal Core made from CRGO Lamination duly annealed to reduce the iron Losses and for the good regulation as voltage drop on load is low due to low resistance of conductor & low leakage flux of toroidal core. Toroidal core will provide stepless, beakless, smooth continuous control linearly proportional to angular rotation. Toroidal core is having high efficiency as no load and full load losses are very low and negligible wave from and power factor distortion due to simple transformer action and excellent short time overload capacity. As Toroidal core is having no sharp edge the breakage of insulation and copper wire can be prevented. the toroidal is wound from metal tape wound on to a mandrel under closely controlled tension, then annealed and treated to develop fully the required magnetic characteristic. It has low electrical resistively, no hysteresis loss, a completely linear B-H Curve and an infinitely high saturation points. this permits the easiest direction of magnetization to be utilized.    

We are endowed with a state-of-the-art infrastructural facility which back us in manufacturing and supplying 3 Phase Variable Auto Transformer. We manufacture this transformer using high quality materials and components, sourced from authentic vendors. It is an energy saving electrical transformer which can convert the voltage as required. Available in different sizes and technical specifications, our 3 Phase Variable Auto Transformer is highly demanded in the market. We offer this transformer at cost effective prices to clients. Key Features: This transformer has strong mechanical strength and short-circuit withstand ability Has a single layer winding on a toroidal core of high grade steel Ideal for over and under voltage testing of electrical and electronic equipment Description: Continously Variable Voltage Auto Transformer is the most effective device for stepless, breakless & continous control of AC voltage & therefore for various parameters, dependent on AC voltage. These Variable Voltage Auto Transformers, consists of a single layer winding on a toroidal silicon-steel core. As the control knob is rotated, a carbon brush traverses the winding, tapping off a portion of the total voltage across the winding. The brush is in continous contact with the winding. The discrete voltage increments obtained as the knob is rotated are always less than the voltage between turns. Since the brush spans more than one turn, the change in voltage is practically continuous. As output voltage is continously variable, Variable Voltage Auto Transformers are rated in terms of current that can be drawn from the output. The basic Continously Variable Voltage Auto Transformers is meant for operation from a nominal input voltage of 240 V I ph AC & can give output voltage anywhere between 0 to 240 v or 0 to 270V AC by simple transformer action. Three such Variable Voltage Auto Transformers 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. Rating Available: 4 Amps- 1600 Amps
