A successful start allowed us to expand our product range by 2013. We began to produce autotransformers. These were single-phase and three-phase models, both very powerful and miniature. A successful combination of technical parameters and excellent marketing allowed us to take the first plac in sales of autotransformers by 2016! All large state corporations work with us!

Three-phase Variac transformer SUNTEK is a powerful and reliable device that is indispensable in production, in workshops and factories. Meter scale and digital voltmeter contribute to the simplicity and ease of operation. The metal case protects the autotransformer from mechanical damage.
The main difference between laboratory autotransformers and conventional ones is that the mobile contact in the winding allows changing the number of turns included in the circuit and thus makes it possible to set the voltage in a wide range, for example, in a single-phase network – from 0 to 300 V, in a three-phase – from 0 to 430 V. the change in The number of turns occurs smoothly, so it is possible to obtain the most accurate voltage values and a pure sine wave at the output. In addition, this device is lighter and more compact than analogues made according to the traditional scheme, and has a much greater efficiency (up to 98%). To control the operation of the control panel has a voltmeter and ventilation grilles in the body contribute to the natural cooling of the device and prevent overheating.

Variac transformer is a type of transformer. The two windings in this device are directly connected to each other. As a result, between them there are two types of communication, one of which is electromagnetic, and the other electric. The coil has several pins with different voltage output values. The difference from conventional transformer is increased efficiency, due to partial change in power.
The autotransformer in our time has found wide application both for industrial purposes and in everyday life. Variac transformer (laboratory autotransformer with manual adjustment) - the need of any radio amateur, allows you to find out the technical characteristics of radio elements, chips, devices and homemade products. Find out the exact characteristics and behavior at different voltages, currents, temperatures will allow experiments and measurements carried out with the help of Variac transformers of low power (test relays, capacitors, microcircuit, working circuit, etc.). Variac transformer SUNTEK with adjustable output voltage from 0 Volt to 300 Volt with LCD display, displaying the output voltage as accurately as the switch variac transformer, is indispensable in these cases.
