    Factory aging test:


    Each laser power supply undergoes ageing test at 60℃ for 12 hours at full load, and 7 seconds power-on and power-off tests for 500 times.

    SPT laser power supply advantages:

    The power supply reaches high efficiency and fast response with its zero current half bridge soft switching circuit, and is easy to cooperate with the co2 laser tube. Terminal control is simple and adapted to high and low level signals. TTL level can be used to control the start and stop of lasers. At the same time, an abnormal protection switch was added to detect whether the external water is ventilated or not.

    Both analog signals of 0 to 5V and PWM signals are ok to control and regulate the laser’s power.

    Power supply open circuit protection functions:

    With good grounding protection, the power supply can work in an open-circuit state for a short time, which can avoid the damage of the laser power supply caused by the bursting of the laser tube.
