This is a PLH - 12000 high power (12 W) proffesional engraving laser head with a PLHD - 12000 driver, thermal protection and PSU. 0,15 x 0,4 mm. Its aluminium body ensures proper heat transfer to other metal parts which cool the laser head. Thanks to its shape it can be mounted to flat surfaces PLHD-12000 driver ensures proper work of the laser head and protect laser diode from overheating. When the laser head reaches 40 degrees Celsius the orange red is starting to glow.
Reaching 45 degrees makes the red diode to glow and driver is switching off the laser diode for as long as the temperature is not lower than 40 degrees. It also sends low signal on the 5th ping on the output wires while in overheat mode. The laser head allows to cut or engrave materials such as wood, paper, leather, cardstock and many other. Thanks to full analog modulation it is possible to engrave in shades of grey or change the output power during turns. High speed modulation (up to 70 kHz) allows to use high movement speed during engraving even complicated patterns.
Module is using brand new NUBM44 450nm diodes (capable of 6W). On this listing PSU 15V 5A is included. Depending on the availability of the PSU from our suppliers, PSU included to the engraving laser head can look a bit different.Anyway all connector pins are always matching PSU send to customer. If you would like to know any details of the PSU please write to us. Modulation inputs can be used as TTL inputs with its logic levels of 0V and 5V or as an analog input. Analog modulation means that by using 2,5 V on ANG input you get 50% output power, analogically by using 4 V you get 80% output power, etc. This unit can work with almost any type of CNC machine, for example: CNC Shark GeckoDrive 540 MYDIYCNC Openbuilds C Beam/OX Shapeoko 2 Shapeoko 3 Stepcraft X-Carve Upgrade X Controller Zen Toolworks Recommendations and requirements.
PLH-12000 must be cooled well because of the heat dissipated on laser diodes. Additional CPU heatsink with fan or attaching PLH-12000 to flat metal surface (part of the machine) should be enough. In situation when temperature is too high yellow led will light on showing that module do not have enough cooling. Remember that adding a fan on heatsink is making its efficiency much better.Remember that it is not a toy. Laser radiation is dangerous even when scattered or reflected from any surface. Always use proper protection laser filter on your CNC machine dedicated to 430 - 480nm in order to avoid reflected radiation. Never point laser head at people or animals. Do not touch the beam, it may cause burns or other injury. Do not stare at the beam or the beam spot while the material is being cut. Laser radiation - Avoid eye or skin exposure to direct or scattered radiation. This module has thermal protection system which protect laser diode from overheating. The analog input is protected by a 5V1 Zener diode on occasion there appears the voltage higher than 5V. Despite everything, this input should not be used with higher voltages. The output of the driver is protected by Shottky diode which doesn't allow the reverse voltage to appear.
