Description

150W ES150 CO2 Laser Power Supply for 130-150W co2 laser tube Engaving Cutting Machine

 

 

Main Features:

 

1) This power supply is specially designed for special laser tube. It makes laser tube output larger and more stable.
2) Quick response speed and good effect: It can enlarge laser power and prolong laser tube’s service life. 
3) Easy Control: The start and stop of laser can be easily controlled by TTL level. 
4) The power supply has output open circuit protection.

5)active PFC function, AC90-250V ultra wide input voltage range, the global general, comes with the voltage regulator function.
6 shell with special profile design, the appearance of stable, beautiful, better heat dissipation, strong anti-interference ability, more perfect embodiment of the characteristics of industrial products.
7)improved current control mode, the light is more stable, better compatibility, better application of various types of laser tube.
80power control is simple, high and low level can be used to control the light.
9)with a manual out of the light button to facilitate testing of laser tube and power supply, troubleshooting easier.
10)cabinet is small in size, and is suitable for mounting on a cutting beam.

Laser power supply maintenance of common sense:

1, Before maintenance, check the power supply shell is normal grounding;
2, measuring power box shell on the work station or whether there is a voltage difference between the workbench
3, power box with high pressure on many places, after power on, hand can’t touch the metal parts of the device
4, Before replace the power box inside device ,turn off the power supply of the energy storage capacitor shall be discharged completely and voltage profile after confirm no voltage for the next step of replacement or repair measures
5, if the laser machine works unstable, or fall of work, can check circuit screw, terminal blocks, such as whether is loose, wiring the phenomenon such as oxidation.the old power supply or the power supply works under poor environment ,pay more attention on formation condition.
6 ,when maintenance,don’t tear down the internal cable tie and connecting wire, control panel, or cut disorderly change, is likely to cause the whole machine interference or performance degradation, and even cause scrap.

 

Fault Analysis of CO2 Laser Power Supply Not Working:

CO2 laser power does not work

(1) Maybe overvoltage protection action:
     A. Please check whether the power supply output and the positive connection of the lamp are reliable!
     B. may be damaged or lamp tube aging, breakdown voltage exceeds 35KV.
(2) Check that the AC input cable and the control wire are securely connected.
(3) Check the high-voltage output line for damage, leakage may lead to power in the work, but the lamp is not light!
(4) Power ground wire (not the power output of the black line but the first port of the AC input terminal see page 3 of the manual) is correct and reliable access to the earth.
