Feature:1. MULTIPLE APPLICATION: Laser module kit can be used for laser cutting machine, laser engraving machine, CNC router, DIY laser, etc.2. EYE PROTECTION: The laser is equipped with a protective cover to protect the user's eyes, and there is no need to wear additional protective glasses. At the same time prevents pets from grabbing the laser spot, more safe to use3. DURABLE ALUMINUM MATERIAL: Laser engraver module adopt good quality aluminum material, which is sturdy and durable. Fixed focus laser is no need to focus4. ENSURE LONG TERM WORK: Aviation aluminum TTL driver board come with cooling fan to ensure continuous long term work, you don't need to worry5. ENGRAVABLE MATERIALS: Can be used for wood, bamboo, cardboard, plastic, leather, PCB board, aluminum oxide, non reflective plating and lacquered metal, nigrescent utility knife6. CUTTABLE MATERIALS: Laser module kit is suitable for cutting cardboard, non woven fabric, veneer, acrylic, some thin plastic sheets7. ACCURATE ENGRAVING: 0.06x0.19mm thin laser focus makes engraving more powerful and accurate, you can use with confidence8. WIDE COMPATIBLE: The transfer board is compatible with 95% of laser engravers on the market, including for ortur, for Neje, for twotree, etc.Specification:Item Type: Laser Engraver Module kitSize: Approx. 40 x 40 x 130mm / 1.57 x 1.57 x 5.12inCircuit Board: 12V PWM modulation boardCircuit Board Size: Approx. 40 x 40mm / 1.57 x 1.57inWorking Temperature: 0~70Working Mode: Pulse workLaser Beam Mode: Fixed focusSpot Size: 30mm1mmOptical Lens: Dia6, glass fiberOptical Output Power: 4.5-5WElectric Power: 40WLaser Wavelength: 450-460nmWorking Current: 1.6-1.8AWorking Voltage: 12VProduct Life: 10000HStorage Temperature: -40~85Plug: EU Plug 100-240VApplication: Can be used for laser cutting machine, laser engraving machine, CNC, DIY laserEngravable Materials: Wood, bamboo, cardboard, plastic, leather, PCB board, aluminum oxide, non reflective plating and lacquered metal, nigrescent utility knifeCuttable Materials: Cardboard, non woven fabric, veneer, acrylic, some thin plastic sheetsLaser Focus: 0.16x0.19mmCompatibility: Compatible with 95% of Laser engraving machines on the market. Includes for ortur, for Neje, for twotree, etc.).Package List:1 x PCB Circuit Board 1 x Laser Host1 x Fixed Focus Plate1 x Power Supply1 x Compatible Board1 x Connecting Wire1 x Wrench and ScrewNote:1. The laser emitted by the laser module is likely to hurt people's eyes, so don't look directly at its end face and wear proper safety glasses to prevent laserirradiation when it is working.2. The laser module requires a suitable laser driver (PCB). When the laser module is connected to the power supply, please set the output voltage to zero. The adjustment of the current should be increased or decreased slowly so as not to damage the equipment.3. Keep the equipment working or stored in a dry environment. The dustproof level exceeds a million to prevent the dust inside the lens from affecting the shape of the laser spot.4. Working at high temperature will increase the threshold current, reduce the conversion efficiency and accelerate the aging of the device.5. When the output power is higher than the specific parameters of its operation, the aging of the equipment will be accelerated.6. When the working temperature of the laser diode exceeds 70 degrees, please do a good job of heating to dissipate it.7. This laser module is an electrostatic sensitive device. Be sure to ground yourself or wear an static proof wrist strap before taking.
