What are the characteristics of high-frequency switching power supply products?
This product is precision machined using imported branded components and internationally advanced full bridge inverter technology, ensuring stable performance and more reliable quality of the entire machine. The whole machine has automatic protection alarm functions for overvoltage, overcurrent, overtemperature, short circuit, and phase loss, as well as soft start function. It can also be equipped with time control and computer interfaces. 3. The DC output waveform is a high-frequency square wave with a ripple coefficient of 1%, which can increase the plating number, reject passivation, enhance the glossiness of the coating surface and the drilling degree of the dark corners of the plated parts. It can also reduce the loss of raw materials and meet various special requirements of the electroplating industry. The 4SFG series adopts an air-cooled design, which is easy to install and equipped with a remote control device, which is easy to operate. It can be switched on and off with a load, reducing the tedious adjustment procedures. 5. It is small in size and light in weight, and the whole machine is made with comprehensive anti-corrosion technology, enhancing the anti-corrosion ability of the product and extending its service life. 6. It is efficient, energy-saving, and the work efficiency reaches 90% or more, and any voltage current ratio is always linearly matched. It eliminates the need for traditional rectifier adjustment. The losses of the compressor and main transformer can save energy by 35% The above greatly reduces the cost of electroplating and is actually the most rational choice in the surface treatment industry
Principle of High Frequency Switching Power Supply
Main circuit
The entire process from AC power grid input to DC output, including: 1. Input filter: Its function is to filter out the clutter existing in the power grid, while also hindering the feedback of the clutter generated by the machine to the public power grid. 2. Rectification and filtering: Directly rectify the AC power grid into smoother DC power for the next stage of conversion. 3. Inverter: Convert rectified DC power into high-frequency AC power, which is the core part of high frequency. The higher the frequency, the smaller the ratio of volume, weight, and output power. 4. Output rectification and filtering: Provide stable and reliable DC power supply according to load requirements.
control circuit
On the one hand, samples are taken from the output end, compared with the set standards, and then the inverter is controlled to change its frequency or pulse width to achieve stable output. On the other hand, based on the data provided by the testing circuit, various protection measures are provided by the control circuit for the whole machine after identification by the protection circuit.
Detection circuit
In addition to providing various parameters that are currently running in the protection circuit, it also provides various display instrument data.
