Rectifier Transformer
The rectifier transformer is the transformer of the rectifier equipment. The characteristic of the rectifier equipment is that the original input current, and the secondary output DC through the rectifier element. Converter is the general name of three working modes of rectification, countercurrent and frequency conversion, and rectification is one of them widely used. A transformer used as a power source for a rectifier device is called a rectifier transformer. Most of the DC power supply for industrial use is obtained from the AC power network through the rectifier transformer and rectifier equipment.
Use of rectifier transformer
Widely used in lighting, machine tools, electrical equipment, mechanical and electronic equipment, medical equipment, rectifier devices and so on. Product performance can meet various special requirements of users.
Protective device
The microcomputer protection device of rectifier transformer is composed of high integration, no bus chip, high precision current and voltage transformer, high insulation strength outlet intermediate relay, high reliability switching power module and so on. It is an economical protection for the integration of measurement, control, protection and communication.
