The high-frequency rectifier is widely used in metal, circuit boards, plastics, foam nickel plating, electrophoresis, oxidation, electrolysis, sewage treatment and other industries. Working principle of product specifications: output DC current: 0 ~ 10A, 100A ...... 30000A optional; output DC voltage: 0 ~ 6V, 12V, 24V ... 600V optional pulse duty cycle: 0 ~ 100% continuously adjustable; pulse Frequency: 0 ~ 20000HZ continuously adjustable; unique aspects: the Minghui switching power supply has three characteristics: 1, and efficient: Key parts of the "Beetle" nano transformer cores using nanocrystalline soft magnetic material, the use of seamless treatment, the copper loss minimal, conversion rates up to 99.5%. Nano-transformer of the "Beetle" was patented in 11 countries in the world, a world leader. Designed a different pulse shape can be requested by the user to adapt to the different metal-plated species to adapt to the plating different shape of the workpiece to achieve the best results. Improve the efficiency of the current speed of plating covering power, to make the coating more dense, smooth, bright, high purity, good uniformity, ductility, wear, corrosion resistance, saving metal materials and additives. 2, the environmental protection: Minghui brand switching power supply shielding, electromagnetic leakage; other power electromagnetic pollution. Volume only 1/5 of the silicon rectifier, weight is only 1/10 of the thyristor, easy planning, expansion, moving, and installation. 3, energy-saving: SCR highest conversion efficiency reached only about 75%, half load or light load case only 55% --- 65%; Minghui brand switching power supply can reach 85% --- 93% power conversion loss is much smaller than the silicon rectifier; product conversion rate, the cooling performance, compared with SCR saving 20% ??-30%, electroplating enterprises to reduce costs will play an important role. Features a stable circuit design, reliability, and good to follow, high stability; very suitable for the needs of electroplating power supply long-term continuous operation. 2, the transformer selected nanocrystalline transformer (the technology has been an international patent, the patent number.: ZL 96 1 09,545.8 international patent Key words: HOIF 27/30, three national patents), the whole loss, high efficiency . IGBT drive using self-developed high-performance driving circuit, the drive power to ensure that the IGBT can work efficiently. , Machine design is reasonable, small size and light weight. 5, compared to the silicon controlled rectifier power supply, saving 20% ??to 30%; than ordinary high-frequency switching power supply power-saving 6% to 10%. 6, can be accessed by remote PLC centralized control, the use of full computer control. 7, the main device using imported materials, highly efficient and stable and durable. The main function of the system features include steady flow / regulator works conversion, over-voltage protection, undervoltage protection, lack of protection, overheating protection, overcurrent protection, etc.. a) steady flow / regulator works conversion. Steady flow regulator works, the system accuracy can be ± 1%. b) Over voltage protection. The system allows the grid range 380 ± 10% V over voltage protection circuit automatically monitoring network power changes when the net electric moment outside the allowable range, the system automatically adjusts the pulse width to ensure the normal operation of equipment. c) lack of protection. Missing running when the power grid failures caused by equipment, the system automatically shut down. d) The over-current protection. When the occurrence of the phenomenon of over-current in the power process, the system can effectively protect the equipment is scheduled to the whole. e) The overheating protection. Extreme deterioration in the event of environmental, internal failure of the ventilation system blockage, ventilation system, cooling surface of the part seriously attached to foreign bodies, etc., resulting in the machine air temperature exceeds the set temperature, the power automatically to stop working at the same time an alarm signal. f) cooling method: air-cooled, water cooled. The Minghui switching power supply electroplating advantages make the coating crystalline detailed, bright, low porosity; the coating in a uniform, leveling; make the deposition speed; can significantly improve the dispersion ability, deep plating capacity; can save the precious metal, saving additives; square wave pulse output for some kinds of plating such as acid copper plating, chrome production effect is a general rectification power supply can not match. 7, anti-corrosion, high temperature: product design unique isolation duct too part of the electronic components installed in the sealed boxes, and taking multiple anti-acid erosion measures to ensure that the erosion of the air from corrosion. Duct and cooling measures to ensure that in the summer high temperature environment, the product can still operate at full capacity, the radiator temperature approach of taking control less than 75 degrees. 8, the maintenance is simple: the product is overall module design and installation. Control board, driver board, panel and computer interface board, so that the design and installation, simple maintenance and low maintenance costs. Maintenance for the easiest fit, As for the replacement of your factory electrician through our guidance, you can maintain real money customers. 9, the design of large power margin: electronic components and an important component leaving a large margin, you can ensure that customers can be loaded with a variety of environments, continuous work. Obvious social benefit: the product has passed the technical appraisal of the Ministry of Science and Technology and the State Administration of Machinery Industry organizations, that the product leading domestic and international advanced. State Power Electronic Product Quality Supervision and Inspection Center to test at full load efficiency of 89%. Actual use will show the product save energy, reduce pollution of the grid, saving metal materials, the effect of significant, it is energy efficient environmentally friendly products.
