The current PCB copying means that on the prEMIse that there are real electronIC products and real circuit boards, reverse analysis of the circuit board is carried out by means of reverse research and development technology, and 1:1 restoration of the original product's PCB documents, PCB bill of materials (BOM) documents, schematic documents and other technical documents as well as PCB silk printing production documents is carried out, and then these PCB technical documents and production documents are used for PCB board making, component welding, flying pin testing Circuit board debugging, complete the complete copy of the original circuit board template.
Power inverter power supply is a new generation of special power supply for power system. It is mainly designed and manufactured according to the characteristics and requirements of power system. It is suitable for the requirements of power system for high quality and reliability of power supply equipment. It is widely used in power system communication, carrier wave, monitoring, relay protection and accident lighting. It can also provide uninterrupted power for AC lubricating electric pumps, AC fans and pumps in power plants. It is widely used in aerOSPace, financial system, office automation control, medical and health, military research and other fields.
Special inverter power supply for electric power. This power supply is made in PWM mode with microprocessor as the core, and is equipped with isolation transformer integration system, highly integrated digital circuit design, pure sine wave output of power frequency isolation transformer, and pure stable output of waveform. It is mainly designed and manufactured according to the characteristics and requirements of power systems such as power plants, substations, power supply bureaus, etc. It can use the existing DC screen of power plants or substations, It forms a special inverter power supply for electric power to realize reliable DC plus reliable inverter power supply, which is widely used in 110VDC or 220VDC power systems.
