It is equipped with all-digital control technology for all kinds of lasers. It has the advantages of low output noise, good current characteristics, stable current, strong anti-interference ability and easy expansion of function. It has anti-overshoot, recoil and Surge of the regulator, constant current dual protection circuit to ensure the stability of the laser work and life. At the same time the drive power supply using LCD liquid crystal display as the device output interface, can provide the power of the various parameters and work status display, with overvoltage, overcurrent, water temperature and water pressure alarm function, also has "data processing, , Fault diagnosis and output control "and other useful features. And all-digital control so that it has a high-precision output at the same time, the failure rate than the traditional power has a clear advantage.
