3D Printer Hotbed MOSFET Expansion Module 2pin Lead For Anet A8 A6 A2 Ramps 1.4 Compatible MOS Tube Power Expansion

*Completely solve the hot bed power is too large and the load current issue *Under the premise of normal cooling, it work stable under I(Max)=20A,   the current must not exceed 20A  while  the process working *If you need anything greater or equal to 15A this module is a must! For example,  if your total power usage is 240W and you have 12V power supply,  then it means at least   20A is needed (20X12=240W). *As ChiTu controller board is only capable of 15A this setting will not work. To make it work,   you need this extra power module. *Dimensions: 60*50mm
