3.Operation Instruction:

 

1)Laser Tube connection: (Referring to Power supply and laser device’s connection diagram- figure
1)High voltage terminal (HV+) of HY-T150 power supply should be connected to the positive pole of CO2
laser device. Current circuit of the power supply shall be connected to negative pole (laser output terminal)
of laser device, through an ampere meter or directly.
2)Connection of control signal
The control signal shall be reliably connected to control terminal of the power supply HY-T150, after
connecting the DAC output signal and TTL signal of external computer with the power supply, the laser
device shall work as expected. If the laser lamp can not work properly, should check the control signal is
correct or not(include check the voltage specification and logic),if use PWM control as power control,make
sure f≥20KHz,Amplitude (peak value) ≤5V,Check and make sure protection switch WP connection is
correct at same time.
3)Voltage of power input:
HY-T150 ‘s power input of the power supply shall be 220VAC/50Hz. If 110VAC is needed, please specify
when placing order.
4)Others:
A group of protection switches are also reserved for detection of water switch, fan switch,
open-enclosure protection and so on.

 

 

4.Caution:

 

1.Water cooling system should be working properly when switching on laser device.
2.Circuit of high voltage output should not be open! (High voltage output terminals (positive and negative
poles) shall be properly connected to positive and negative poles of laser device, respectively.)
3. Attentions should be given to avoid any electric shock after the power supply being switched off.(The
Insulation safety requirements should be 40KV between the terminal of output and “G”)
4. Well-grounded three-pole receptacle should be used to supply power to HY-T150 power supply. The
enclosure should be well grounded to avoid electric shock.

 

 

 

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.
