2pcs 3D Printer Hotbed Heating Controller Heated Bed Power Expansion MOSFET MOS Module Compatible for Anet A8 A6 A2 3D Printer (Black)

Features:
Completely solve the hot bed power is too large and the load current issue, compatible for Anet A8 A6 A2 3D Printer.
Under the premise of normal cooling, it work stable under the maximum current of 25A, the current must not exceed 25A 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.
Functional test has been done for each module, you can use it safely.
