Product Features of High Frequency Switching Power Supply
This product adopts imported famous brand components and international advanced full-bridge inverting converter technology to make precision processing, which makes the performance of the whole machine stable and the quality more reliable. 2 The whole machine has overvoltage, overcurrent, overtemperature, short circuit, lack of phase automatic protection alarm function and soft start function. It can also be equipped with time control and computer interface. 3 The DC output waveform is a high-frequency square wave, and the ripple coefficient <1[%], which can increase the number of plating, reject passivation, enhance the gloss of the coating surface and the core drilling degree of the dark corner of the coating. It can also reduce the loss of raw materials and meet various special requirements of the electroplating industry. The 4SFG series adopts air-cooled design and is easy to install. And equipped with remote control device, easy to operate. The machine can be turned on and off with load, reducing the cumbersome procedures of adjustment. 5. Small in size and light in weight, the whole machine is made with all-round anti-corrosion technology, which enhances the anti-corrosion ability of the product and prolongs the service life. 6 High efficiency, energy saving, working efficiency above 90[%], any voltage-current ratio is always linearly matched. It saves the loss of the voltage regulator and main transformer of the traditional rectifier, saves energy by more than 35[%], and greatly reduces the cost of electroplating. It is actually the most rational choice for the surface treatment industry.
According to the TRC control principle, there are three ways:
1. Pulse Width Modulation
The switching period is constant, and the duty cycle is changed by changing the pulse width.
Second, pulse frequency modulation (pulseFrequencyModulation, abbreviated as pFM) conduction pulse width is constant, by changing the switching frequency to change the duty cycle.
3. Mixed modulation conduction pulse width and switching frequency are not fixed, and both can be changed. It is a mixture of the above two methods. The high-frequency switching power supply can theoretically reduce the switching loss to zero without greatly increasing the switching speed, and the noise is also small.
