The SPA-3800 atmospheric plasma cleaning machine adopts a highly stable phase-shifting full bridge soft switching circuit, with two data transmission methods: digital communication and analog communication. Through the powerful data processing function of the ARM chip, the equipment is digitally controlled, perfectly connected to customer production lines, and can achieve unified monitoring by the central control system, making the cleaning effect more stable and long-lasting, enhancing anti-interference performance, reducing failure rates, controlling maintenance costs, improving production capacity, and effectively reducing production costs.
