Which Shenzhen family company production of switching power supply of good quality?

Looking for good quality switching power supply, we recommend selecting Shenzhen city run Sheng Feng power science and technology limited company, Shenzhen city run Sheng Feng Power Technology Co., Ltd. was established in 2011, is a" switching power supply, switching power supply adapter" professional production factory, our factory passed ISO 9001 international quality management system certification, and always follow the ISO spirit in production management. And is now actively import ERP management system, its purpose is to hope is to ensure that our products maintain both high quality and can reduce the cost, in order to provide better customer service and more competitive products. We engaged in power equipment research, development, production and sales of integrated enterprise, the main products for the switching power supply adapter, charger, power supply, the product has a comprehensive import RoHS&WEEE process. Shenzhen city run Sheng Feng power science and technology limited company is a professional development, design, production of high-frequency switching power supply Taiwan-funded enterprises. Has imported wave pipeline, welding lines and all kinds of advanced testing equipment, strong production capacity, technology development, design strength. In Shenzhen, Shenzhen AC switching power adapter switching power supply adapter, Shenzhen industry leading edge. According to the excitation signal can be divided into structural classification; pulse width modulation and pulse amplitude modulated two, pulse width modulation control signal width, or frequency, pulse amplitude modulation of the amplitude of the control signal, the effect of both the same is that the oscillating frequency is maintained in a certain range, stable voltage effect. The winding of the transformer can be generally divided into three types, one group is involved in the oscillation of the primary winding, a group is to maintain oscillation feedback winding, and a group of load winding. The soft switch technology makes DC / DC produced qualitative leap, the United States of America VICOR company to design and manufacture of a variety of ECI soft switch DC / DC converters, the maximum output power of 300W, 600W, 800W, corresponding to the power density ( 6.2, 10, 17) W / cm3, efficiency (80 ~ 90 % ). The Japanese company NemicLambda is the latest of a soft-switch technology of high frequency switching power supply module RM series, the switching frequency ( 200 ~ 300 ) kHz, power density has reached 27W / cm3, using synchronous rectifier ( MOS? FET instead of Schottky diodes ), making the entire circuit efficiency to 90%. The AC / DC high-frequency switching power supply, switching power supply with high reliability, high power density, strong anti-interference ability, beautiful and practical design for the expertise, more than 3KW high power switching power supply using phase-shifted full-bridge soft switching circuit. This kind of switch power supply can be widely used in digital circuits, industrial instrumentation, communications equipment, transportation industrial machine and other large equipment and scientific research and experiment for DC power supply. This kind of switch power supply output voltage, current can be arranged as required ( adjustable ), and a single road, multiple optional, positive, negative input custom, single-phase, three-phase is not restricted, shape and size according to the actual order.
1 of the products imported brand-name components and the international advanced full bridge inverter commutation technique of precision machining, the machine stable performance, more reliable quality.
2 machine has over-voltage, over-current, over-temperature, short circuit, lack of equal protection of automatic alarm function and soft starting function. And can be additionally provided with a time control and computer interface.
The 3 DC output waveform to a high frequency square wave, ripple factor < 1%, can increase the number of plating passivation, refuse, enhanced surface gloss and plating the dark corner of the core drilling. And can reduce the loss of raw materials, all kinds of special requirements to the electroplating industry.
4 SFG series of high-frequency switching power supply using air-cooled design, convenient installation. And with a remote control device, simple operation. Can load switch machine, reduce the adjusting the cumbersome procedures.
5 has the advantages of small volume, light weight, the use of the full range of anti-corrosion technology of production, enhance the product corrosion resistance, to extend the service life.
6 efficient, energy saving, work efficiency achieves 90% above, any voltage current is always linear matching. Unlike the conventional rectifier voltage regulator and the main transformer loss, energy saving in 35% above, greatly reduce the cost of electroplating surface treatment industry, it is the most sensible choice.
