???? ???????? 40W CO2 Laser Power Supply for CO2 Laser Engraver Cutter MYJG, 110/220VAC CO2 Laser Engraving Cutting Machine Power Supply

--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.
