SPA-5800, as the first initiate "full digital atmospheric plasma cleaner" in China, has comprehensive digital control functions, which can digitally monitor and control air pressure, power, speed of revolution, and grid voltage.Real-time monitoring of air pressure, power, speed, and grid voltage and display on the software interface. Precisely set air pressure, power, reduce interference, strong stability, and make human-computer interaction easier.

2.ARM chip with powerful high-speed central processing power·All atmospheric plasma cleaners on the market do not have ARM chips, and cannot implement complex human-machine interaction, and cannot intelligently judge and uniformly process data.·SPA-5800 uses ST-branded ARM chips, as if equipped with a "brain". Make human-computer interaction simple and clear, with powerful remote debugging communication functions, can be seamlessly connected to any application scenario; independently developed software to intelligently judge and coordinate work on real-time collected data, can realize power self-matching, stable and unchanged；

·Most of the atmospheric plasma cleaners on the market use analog circuits. The circuits are complex, and the power factor can only reach 0.65. There is a large amount of loss, which causes the equipment to overheat and cause interference to the external network. Also, the fluctuation of the grid voltage will cause a large output power change.

·The SPA-5800 is equipped with a PFC module, which can compensate and correct the circuit. The simple circuit design can improve the power factor to above 0.9, 50% quota power ≥0.95, 100% quota power ≥0.99. Effectively reduce power consumption and heat generation, have low requirements on grid capacity, effectively control the load and interference caused to the grid, and save energy, environmental protection and stability.

4.Digital control power self-matching, adjustable power range expanded by 4 times

·The power adjustment range of atmospheric plasma cleaner for analog circuit is small. Generally, the adjustable power range of atmospheric plasma cleaner equipped with jet spray gun is 200W-500W, while the adjustable power of rotary spray gun is 500W-700W. Power adjustment by knob, large error, low accuracy, power accuracy is ± 5%, and the actual working power cannot be understood and judged in real time;

·SPA-5800's adjustable power range is 200W-1000W, with a large adjustable power range. And equipped with an ARM chip, it can realize fast self-matching of set power, power accuracy is ± 1%, stable and unchanged, will not cause the actual working power to change due to air pressure fluctuations, network voltage fluctuations, and nozzle gun and electrode aging, ensure uniform and stable cleaning effect;

·Monitor the actual working power of the plasma in real time and display it on the system interface.
