    Tips:

    The control transformer is mainly used for "control", mainly to change the primary voltage to the voltage suitable for the electrical control circuit. For example, for the safety of lathe operators, the lathe control circuit is generally reduced to 36V safe voltage. Here we need a 380/36V control transformer. Of course, such a control transformer also has the function of isolation, because it also needs to separate the primary and secondary into two unrelated systems. Moreover, the distributed capacitance of 380V system can be ignored, and the primary and secondary insulation problems are not very large. But it can't be called an isolation transformer.

    The control transformer has a wide range of uses, which can be used as a step-up or a step-down in the low-voltage distribution system. The control transformer is named because it is mostly used in the control system. It can be a step-down transformer with various output voltages, and can also be used as the power supply for low-voltage lighting, signal lights and indicator lights.
