Laser Power Supply

Feature:

1.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, et

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

3.The power supply has the function of open circuit protection: Under the condition of good protective in earth, the power supply can work in open-circuit condition 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.

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

5.Aging testing 500 times starting and stopping in 30 ℃ and 12 hours circumstance.                                               

6. Application: CO2 laser power supply are mainly applied in engraving & cutting machine, laser marking machines and medical laser machine.       

Technology Paremeter:        

Installation                                                    

Connection of laser tube, the high voltage (HV+) of the laser power supply shall be connected to the anode (full reflection terminal) of CO2 laser tube.

The current circuit of the laser power supply is connected to the cathode (laser output terminal) of CO2 laser tube through an ammeter (or directly).                                     

2. Connection of control signal：Control signal shall be reliably connected to control terminal of the power supply.                                                   

3. Input of control signal: After connecting the output signal and TTL signal of external computer with the power supply, the laser tube shall work as expected.   

                             
Cautions:　                                                    

1. Ensure that laser power should be place is well ventilated, it is strictly prohibited that the louver of laser power close to machine (the distance would better more than 3 cm).      

2. HV output terminal shall not adopt open circuit! (HV output terminals shall be properly connected to the anode and cathode of the laser tube), High voltage connector and wire connection joint should not to be stressed and pulled etc.                                                    

3. Discharge resistance has been equipped inside the power supply and the residual voltage will be fully discharged 2s later after power off. Attentions should be given to avoid any electric shock! (Both output terminals of the high voltage shall ensure the isolation safety of the overhead 40KV.)                                                

4. Three-poles socket with earth contacts shall be used to laser power supply. The enclosure should be well grounded to avoid electric shock.                                                

5. Pay attention to the maintenance of the laser power, please cleaning the dust of power supply and cooling fan regularly                                                

6. Ensure the laser power integrity. it is strictly prohibited to destroy the high voltage connector, the cable and labels, etc.
