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.
