Occupying a very important position in the power transmission and distribution system, it is required to operate safely and reliably. When the Low price control transformer is damaged during operation, it will cause a power outage. It is usually used in machine tools and mechanical equipment as the power supply of electrical control lighting and indicator lights, and is used to provide power for the control part of the electrical circuit.
Working principle of control transformer.

There is no difference between low price control transformer and ordinary transformer in principle, but the purpose is different. The control transformer has a wide range of uses and can be used for both step-up and step-down.

The working principle of the Low price control transformer is based on the principle of electromagnetic induction. A transformer has two sets of coils. primary coil and secondary coil. The secondary coil is outside the primary coil. When the primary coil is supplied with alternating current, the transformer core generates an alternating magnetic field, and the secondary coil generates an induced electromotive force. The turns ratio of the coils of the transformer is equal to the voltage ratio. For example: the primary coil is 500 turns, the secondary coil is 250 turns, the primary is connected to 220V AC, and the secondary voltage is 110V. The Low price control transformer can step down or boost the voltage.
