Description
The control transformer is mainly suitable for AC 50 Hz (or 60 Hz), voltage 1000 V and below, and can work continuously for a long time under rated load. Usually used in machine tools or mechanical equipment as electrical control lighting and indicator power supply.
In the low-voltage distribution system, the control transformer is often used in the control system. It is actually a step-down transformer with a variety of output voltages, and can also be used as a power supply for low-voltage lighting, signal lights, and indicator lights.
The control transformer has the characteristics of small size, safe and reliable wiring, high protection level, good performance, and can work effectively in the rated load for a long time.
Working principle
The control transformer works on the principle of electromagnetic induction. The transformer has two sets of coils. Primary and secondary coils. The secondary coil is outside the primary coil. When the primary coil is connected with alternating current, the transformer core produces an alternating magnetic field, and the secondary coil produces induced electromotive force. The turn ratio of the transformer coil is equal to the voltage ratio
