- Frequency: <15khz, PWM/TTL: 0-5V , Please add a fan when engraving or cutting, in case smoke damage its lens.
- Please press the button on the driver board to get it work!
- When you connect this module to your controller board, please pay attention to the pin positions of 12v+ GND- and PWM/TTL, red wire=12V+, black wire=GND-. Yello wire=PWM+, white wire=PWM-(3-4pin wire). So Red Wire must be connected to the 12v+ pin on your controller board’s interface, Black Wire Must be connected to the GND- pin and Yellow Wire must be connected to the PWM/TTL pin, if you use 3-4pin wire, White wire should be connected to the PWM- pin.
- if your controller board’s interface pins are in different position, please change the wires position to make it match the positions of + - PWM of your interface. If the wires connected wrong, it will damage the diode and the driver board.Use a 12V 3A+ DC adater connect with the 3Pin-DC cable, you will be able to connect it to 110-240V power source directly! And don't forget to press the on/off button on the driver board to get it work!
- Wavelength: 450nm, Output: 3.5 , (W), can engraving & marking on wood, leather , cardboard and plastics.
