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. Plywood 10mm: 300mm/min 5W 10 passes (1 pass for each mm). Vinyl 2mm: 100mm/mi 5W 1 pass (the smoke must be removed quickly). Red Plexyglass 3mm: 100 mm/min 4 passes (no smoke).
Other speeds and materials: Wood 3mm: 200mm/mim 5W 3 passes (1 pass for each mm) InchJet Photographic paper: 400mm/min 5W 1 pass Paper: 600mm/min 2W. Caution: 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.Do not stare at the beam or the beam spot while the material is being cut. Recommended power supply: 7,5V 5A. 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.
