3D Printer hotbed MOSFET expansion module inc 2pin lead A8 A6 Compatible4624\n\nIt very often that after purchasing 3D printer (especially in Anet A8, A6, A2) motherboard is all load to heat up Printing Hotbed. That creates fire hazard problems as connectors are not suitable for that high loads.\nHence that issue MOSFET Module is solving existing problems by taking the load off the motherboard. \nIt also solving print quality issues as motherboard is not heavily overloaded with power consumption of heating printbed.\nIt is used not for hotbed only. It is very common that it is used for extruder's heating elements . \nMAinly it is to take the load off the motherboard and make motherboard more stable and power interference free.\nColor: Black\nMaterial: plastic\nIf your total power usage is 240W and you have 12V power supply, then it means at least 20A is needed (20X12=240W). \nAs controller board is only capable of 15A this setting not work. To work, you need this extra power mod.
