Heated bed power module Based on powerful MOSFET HA210NO6 Size: 60*50mm Mounting holes: 3.2mm diameter, for M3 screws. Distance between holes: 54*43mm Very powerful MOSFET to withstand higher current than normal RAMPS or other 3D Printer controller can handle Voltage: 12V-24V Under the premise of normal cooling, it work stable under I(Max)=25A, the current must not exceed 25A while the process working
