DY20 150w Co2 Laser Power Supply For Co2 Laser Engraving and Cutting Machine

Model: HY-DY20

1.Main Features：

1. This power supply is specially designed for special laser tube.the power supply makes laser tube output larger and more stable.

2. Quick response speed and effect,high performance,large cutting power,it also can prolong laser tube 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. The power supply has TTL signal indication, water through signal indication and laser output indication.

6. This power supply has the Buttonto test output laser manually.

7. Application: Sculpture and cut acrylic,fabric,double color sheet and rubber etc.

Environment		Operating temperature: (-10-40)degree Celsius,Relative humidity: ≤90%
Cooling		Forced air cooling (fan cooling)

3.Operation Instruction:

1)Laser Tube connection: (Referring to Power supply and laser devices connection diagram)
High voltage terminal (HV+) of HY-DY20 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-DY20,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-DY20 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 50KV between the terminal of output and
"G")
4. Well-grounded three-pole receptacle should be used to supply power to HY-HVCO2/1.6 power
supply. The enclosure should be well grounded to avoid electric shock.

The instruction of Power supply and laser wiring diagram and terminal:

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 cant 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.​
