oxlasers powerful 450nm 15W 15000mW blue laser module DIY laser head for CNC laser engraving machin
[32958037528] Technical Parameters: Laser wavelength: 445nm-450nm blue laser Spot type: retangle spot (fixed focus, NOT FOCUSABLE) Size: 40*70mm Drive mode: external ACC constant current drive Cooling method: forced air cooling Operating voltage: 12V DC Control interface: 2 * 2.54 ( PWM control power) Shell material: aluminum, surface anodized Collimator lens: optical glass coating THIS IS NOT A FOCUSABLE LASER, this laser is for CNC laser engraving machine or laser cutter only!! PACKING LIST: LASER*1 3PIN CABLE*1 3pin-4pin cable*1 SAFETY GLASSES*1 BUYER MUST READING: When you connect laser 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 laser 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. Please add a fan when you engraving or cutting, in case smoke blur the lens damage the lens
