The laser power supply of the fiber laser marking machine is a device that provides power for the fiber laser, with an input voltage of AC220V alternating current. Installed in the control box of the marking machine. The fiber laser marking machine adopts an imported pulse type fiber laser, which has a good output laser mode and a long service life. It is designed and installed inside the marking machine casing. The galvanometer scanning system is composed of two parts: an optical scanner and a servo control. The entire system is designed and manufactured using new technologies, materials, processes, and working principles.
