Aviation aluminum TTL drive board with cooling fan to ensure continuous long-term work. 6. Engraveable materials: wood, bamboo, cardboard, plastic, leather, PCB board, aluminum oxide, non-reflective electroplated coating and lacquered metal, blackened utility knife. 7. Cuttable materials: cardboard, non-woven fabric, veneer, acrylic, some thin plastic boards. 8. 0.08*0.1mm four-compression light point coupling technology, more powerful and precise engraving. 9. The engraving speed is 200% higher than other 10W lasers. 10. High energy can cut 8.5mm thick plate at one time. 11. The laser sintering temperature is 2400 degrees, and the effect of engraving metal is better. 12. The laser has a built-in horizontal gyro anti-dumping protection device, and it stops working when the inclination angle is 20°. 13. The wind collecting hood can remove smoke and dust, protect the lens and avoid laser energy attenuation. 14. The transfer printed circuit board is compatible with 95% of the laser engraving machines on the market, including Atomstack, ortur, Neje, twotree, etc. Specifications: Brand: Atomstack Optical output power: 20-21W Product material: Aluminum 6061 Anode Shell size: 140*65*60mm Circuit board size: 44*52mm Circuit board: V/PWM modulation board Wire: 22#2P2.54 terminal reverse wire 80mm Optical lens: 6/glass Fan: 24V Laser beam mode: point Working mode: pulse work Spot size: 0.08*0.1mm Working hours: 10000H Working temperature: 0℃-70℃ Storage temperature: -40℃-85℃ Sintering temperature: 2000-2400℃ Product net weight: 715g Bullets: Min Typ Max Unit Condition Optical output power: Po 9.5 10 W 24V power supply Working current: Iop / 2.9 3.2 A Working voltage: Vop / 24 / V Laser wavelength: p 455 460 nm Electric power: Wl / 69.6 76.8 W Precautions: 1. The laser emitted by the laser module is easy to hurt the eyes. Do not look directly at the end face when working, and wear suitable protective glasses to prevent laser. 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 current adjustment should be increased or decreased slowly to avoid damage to the device. 3. Keep the device working or storing in a dry environment. The dust-proof rating exceeds one million, preventing the dust inside the lens from affecting the shape of the laser spot. 4. High temperature operation will increase the threshold current, reduce conversion efficiency and accelerate device aging. 5. When the output power is higher than its specific operating parameters, it will accelerate the aging of the device. 6. When the working temperature of the laser diode exceeds 70 degrees, please do a good job of heat dissipation. 7. This laser module is an electrostatic sensitive device. Please ensure that your body is grounded or wear an anti-static wrist strap before use. Notes: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Please allow 1-3mm measuring deviation due to manual measurement. Thank you for your understanding!
