CO2 Laser Tube Power Supply ( 40 watts )

CO2 Laser Tube Power Supply ( 40 watts )

40W CO2 Laser Tube Power Supply special designed for 30W - 50W CO2 Laser Tube and mini laser engraver, laser stamp engraving machine, very small volume and weight, very long warranty and lifetime.


1. The Main Feature:

1) Good compatibility: It can be applicable to 30W, 40W, 50W laser tube.

2) Fast response speed and effect.

3) Dramatically lengthen the life of laser.

4) Easy Control: The start and stop of laser can be easily controlled by TTL level. And there are protection switch to test the external water, ventilation, etc.

5) Easy control of laser power: Both 0-5V analog signal and PWM signal can control the laser power.

6) The power supply has open circuit protection: Under the condition of good protective earth, the power supply can work in open-circuit for a short time, which could avoid the damage of laser power supply because of the bursting of laser tube, thereby enhancing the life of power supply.

7) The power supply can take feedback interface which can be used in closed-loop control and testing the working current of laser.

8) The power supply adds a new function, that is timely scene judging which part is damaged, laser tube or laser power.

9) Application: Acrylic sculpture, cut; Fabric sculpture, cut; Rubber sheet sculpture, cut, etc.
