With the rapid and flourishing development of the high-tech industries worldwide, the development of various types of precision machines and equipment has expanded in scale. Relative to the precision mechanical equipment and processes such as IC semiconductor, CNC machines, precision laser cutting, EMS, PCB production equipment, PLC program control, microelectronics production, SMT, computer automation, etc., the high-tech industries’ massive use of computer and precision equipment has led to power and voltage equipment’s high sensitivity to power and voltage changes because excessive changes in the voltage are likely to result in abnormal operation, breakdowns, and even frequent crashes. With professional technological designs, planning, and production power-saving and energy-conservation transmission and distribution systems, Yu-Sheng Electrical endeavors to ensure the security, stability, and accuracy of the precision equipment and stabilize the power voltages in order to address and ensure the efficient implementation of the equipment functions. Yu-Sheng leads the world by means of its specialized electrical and mechanical engineering. All the production processes from raw material preparation, coil winding, silicon steel stacking, assembly, drying, testing, to product shipments undergo vertical production. Yu-Sheng’s main products include: voltage regulators, microcomputer regulators for precision equipment, electronic voltage regulators for precision equipment, high and low voltage transmission and distribution transformers, reactors, mechanical control transformers, and other products. Yu-Sheng Electricals has always endeavored to diversify its power supply and electronic equipment related technologies. Through continuous innovation and R&D, it aims to meet the demand of the energy-saving environment. Adhering to “customer first,” our ultimate goal is to offer post-sale services through dedicated efforts. to solicit agent and dealer
