ATO Toroidal Transformers is one of the transformers series at Steptransformer.com. The annular transformers on our website are mainly one-way step-down transformers. Customizable capacity from 50 VA to 5000 VA. Main coil voltage for 110V/ 120v / 220v / 230v / 240v, the secondary coil is 12v / 24v/ 48v / 110v / 220v / 2x6v / 2x12v / 2x24v / 2x30v / 2x35V/ 2x40V/ 2x50V. The role of ATO toroidal transformer is generally the effect of lifting voltage, usually we use a variety of voltages, such as life lighting is 110 volt, industrial safety lighting is 36 volt, the voltage of the welding machine also needs to be adjusted, these are separated from the toroidal transformer. Through the principle of electromagnetic mutual induction between the primary and secondary coils, the step down transformer can reduce the voltage to the voltage we need. In the long-distance voltage transmission process, we need to increase the voltage to very high, in order to reduce the voltage loss, usually increased to several thousand volts or even tens of thousands of volts, this is the role of the step up toroidal transformer.
