<b>--Application: Engraving, seal-cutting, etc. </b><br> <b>--Protection switch: test the external water, ventilation, etc., to protect laser device</b><br> <b>--TTL voltage level control: can be set high or low lever</b><br> <b>--Easy control: the start and stop of laser can be easily controlled by TTL level.</b><br> <b>--New function: timely scene judging which part is damaged, laser tube or laser power.</b><br> <b>--High Security: input and output of power supply are separated completely to avoid getting an electric shock.</b><br> <b>--Open circuit protection: with well-grounded enclosure, the power supply can work in open-circuit for a short time, <br>which could avoid the damage of laser power supply because of the bursting of laser tube, thereby enhancing the life of power supply.</b><br><br> <b>Pin Definition: </b><br><br> <b>*P1: </b><br> 1--L-: Connect Negative Electrode of Laser Tube. <br> 2--FG: Connect with G Internal, and Connect the Power Supply Shell. <br> 3&4--AC AC: AC 110V/220V Input. <br><br> <b>*P2: </b><br> 1--G Signal Ground:The foot must connected with laser machine's enclosure and ground properly. <br> 2--P Input Signal:Water Protction Switch. <br> 3--L Input Signal:The control of laser: Low Level, emitting laser.<br> 4--G Signal Ground : The foot must connected with laser machine's enclosure and ground properly. <br> 5--IN Input Signal :Laser Power supply control terminal can use 0-5V Analog Signal Control,also can use 5V PWM Signal to Control. <br> 6--Output Power: 5V,Max output Current 50mA. <br><br> <b>*P3: </b><br> 1--24V:output 24V,Max Current 2A,power for master board. <br> 2--G:24V and 5V Ground. <br> 3--5V:output 24V,Max Current 1A. <br> 4--L:The control of laser: Low Level, emitting laser.<br> <br>Note: the standard laser power supply is with 220V, if you need 110V, you can do adjust the Voltage switch of the side.</b><br><br>
