Input from the AC power grid, DC output of the whole process, including: 1, input filter: its role is to filter the presence of grid clutter, but also impede the machine generated by the clutter feedback to the public grid. 2, rectification and filtering: the grid AC directly rectified into a smoother DC for the next level of transformation. 3, inverter: rectified DC into high-frequency alternating current, this is the core of the high-frequency part, frequency The higher the frequency, the smaller the ratio of volume, weight and output power.4. Output rectification and filtering: according to the needs of the load, provide a stable and reliable DC power supply.
Provides power supply for different requirements of all single circuits. Switching control voltage regulator principle switch K to a certain time interval repeatedly on and off, in the switch K on, the input power supply E through the switch K and filtering circuit to provide the load RL, in the whole switch on period, the power supply E to the load to provide energy; when the switch K off, the input power supply E will interrupt the provision of energy. It can be seen that the input power supply to the load to provide energy is intermittent, in order to enable the load to get continuous energy supply, switching regulated power supply must have a set of energy storage device, a part of the energy will be stored when the switch is turned on, when the switch is disconnected, to the load release. In the figure, the circuit consisting of inductor L, capacitor C2 and diode D has this function. Inductor L is used to store energy, and when the switch is disconnected, the energy stored in inductor L is released to the load through diode D, so that the load receives continuous and stable energy, because diode D makes the load current continuous, so it is called a continuity diode. The average value of the voltage between AB EAB can be expressed in the following formula: EAB=TON / T * E in which TON for each time the switch on time, T for the switch on and off the operating cycle (i.e., switch on time TON and off time TOFF and the sum). As can be seen from the formula, change the switch on time and the proportion of the operating cycle, the average value of the voltage between the AB also changed, therefore, with the load and the input power supply voltage changes automatically adjust the proportion of TON and T will be able to make the output voltage V0 to maintain the same. Changing the on-time TON and the proportion of the operating cycle is also to change the duty cycle of the pulse, this method is called "time ratio control" (TimeRatioControl, abbreviated as TRC).
This product adopts imported brand-name components and international advanced full-bridge inverter current converter technology precision processing, so that the performance of the whole machine is stable and the quality is more reliable.2 The whole machine has over-voltage, over-current, over-temperature, short-circuit, lack of phase, such as automatic protection and alarm function and soft-start function.

It can also reduce the loss of raw materials and meet various special requirements of electroplating industry.4SFG series adopts air-cooled design, which is easy to install. And equipped with remote control device, easy to operate. It can switch on and off the machine with load, reducing the cumbersome procedure of regulation.5. Small volume, light weight, the whole machine uses a full range of anticorrosion process production, enhancing the corrosion resistance of the product and prolonging its service life.6 High efficiency, energy saving, the working efficiency reaches more than 90 [%], and the arbitrary voltage-current ratio is always a linear match. Save the traditional rectifier regulator and the loss of the main transformer, energy saving in more than 35 [%], greatly reducing the cost of plating, is the most sensible choice for the surface treatment industry.
