The Introduction Of High Frequency Switching Power Supply Introduction: High frequency switching power supply (also called switch rectifier SMR) through the MOSFET or the high frequency IGBT, switch frequency control in 50-100 KHZ, within the scope of efficient and realize miniaturization. In recent years, switch rectifier power capacity expansion, the capacity of himself, from the volt 48V/12.5A、48V/20A to48V/200A、48V/400A。 High frequency switching power supply is traditional rectifier (silicon rectifier, silicon-controlled rectifier) upgrade alternative products. High frequency switching power supply with convenient use, small size, high efficiency, stable work, coating meticulous etc absolute superiority quickly dominate the market. Widely used in electroplating electrolysis surface treatment industry oxidation and get old and new customers. Product features: 一．This product USES imported brand components and international advanced bridge in precision machining technology of inverter, and make the performance is stable, the quality is reliable. 二．For high-frequency pulse waveforms output ripple coefficient, the 1%, can improve the number of plating and surface aestivation, refuse the gloss and got a dark corner of plating. And can reduce the loss, raw materials of plating industry of special requirements. 三．SFG series high frequency switching power supply by air-filled type design, installation convenience. With remote control device, easy for operation. Can bring load switch machine, reduce the adjustment of the complex procedures. 四. Small volume light weight the comprehensive use of anticorrosive craft, enhance the ability of anti-corrosion products, prolong the life. 五. Energy saving, high working efficiency reached more than 90%, any more than a linear always voltage matching. Save the traditional rectifier regulator and the energy loss, in more than 35%, greatly reduce the cost, the reason of surface treatment industry High frequency switching po
