Product: 40W CO2 Laser Power Supply for CO2 Laser Engraver Cutter MYJG, 110/220VAC CO2 Laser Engraving Cutting Machine Power Supply
Brand: Ketofa
--Application: Engraving, seal-cutting, etc. 
 --Protection switch: test the external water, ventilation, etc., to protect laser device
 --TTL voltage level control: can be set high or low lever
 --Easy control: the start and stop of laser can be easily controlled by TTL level.
 --New function: timely scene judging which part is damaged, laser tube or laser power.
 --High Security: input and output of power supply are separated completely to avoid getting an electric shock.
 --Open circuit protection: with well-grounded enclosure, 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.

 Pin Definition: 

 *P1: 
 1--L-: Connect Negative Electrode of Laser Tube. 
 2--FG: Connect with G Internal, and Connect the Power Supply Shell. 
 3&4--AC AC: AC 110V/220V Input. 

 *P2: 
 1--G Signal Ground:The foot must connected with laser machine's enclosure and ground properly. 
 2--P Input Signal:Water Protction Switch. 
 3--L Input Signal:The control of laser: Low Level, emitting laser.
 4--G Signal Ground : The foot must connected with laser machine's enclosure and ground properly. 
 5--IN Input Signal :Laser Power supply control terminal can use 0-5V Analog Signal Control,also can use 5V PWM Signal to Control. 
 6--Output Power: 5V,Max output Current 50mA. 

 *P3: 
 1--24V:output 24V,Max Current 2A,power for master board. 
 2--G:24V and 5V Ground. 
 3--5V:output 24V,Max Current 1A. 
 4--L:The control of laser: Low Level, emitting laser.
 
Note: the standard laser power supply is with 220V, if you need 110V, you can do adjust the Voltage switch of the side.


[Specificity and Good compatibility]-- It is designed exclusively for Engraving Machine and can be applicable to 40W and 30W laser tube of a number of manufacturers. Quick response speed.
[Perfectly performance] --Large cutting power.Powerful Features and High Integrity. It makes the high-pressure laser power supply, driving control board and the auxiliary power of drive motor integrate in one board, so as to reduce external lead and strengthen the anti-interference ability.
[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. Moreover the laser power conversion can be controlled by a potentiometer.
[Advanced Technology]--The power adopts Soft Switch Technology, so dramatically increase the efficiency of the power supply, boost reliability of the power supply and also lengthen service life of laser. Can timely scene judging which part is damaged, laser tube or laser power.
[High Security]--The input and output of power supply are separated completely to avoid getting an electric shock. with well-grounded enclosure, the power supply can work in open-circuit for a short time, which could avoid the damage of laser power supply .
