Constant voltage transformer is an ideal regulated power supply for precision electronic instruments, microcomputers and CNC equipment. There is a "day" shaped iron core in the constant voltage transformer. The primary coil is in one window ...

When the transformer is powered on, there is a buzzing sound, which is mainly the function of high-voltage magnetic flux. During normal operation, the sound of the transformer is uniform. When there are other noises, carefully check the caus...

A transformer is a device that converts the voltage so that the high voltage is reduced or the low voltage is increased. It is a device that converts AC voltage, AC current and impedance. In order to ensure the normal operation of different ...

The output of rectifier transformer is still AC, which only provides power for rectifier equipment. Usually, the primary side is connected into a star shape and the secondary side is connected into an angle shape to suppress high-order harmo...

Box type transformer is a general term for the transformer system installed in the box （as protection）， which is divided into three parts: ① high voltage switch control room; ② Transformer room; ③ Low voltage switch control room...
