Addresses the common issue of 3D printer motherboards (especially in Anet A8, A6, A2 models) being overloaded by heating the printer's heatbed, which can pose fire risks due to inadequate load capacity. This MOSFET module resolves these problems by offloading the strain from the motherboard. It also improves print quality by preventing motherboard overload from the heatbed's power consumption. While commonly used for the heatbed, it's also effective for the extruder's heating element. Its primary function is to stabilize the motherboard and prevent power interference. Color: Black Material: Plastic Calculation Example: If your power consumption is 240W and you have a 12V power supply, you need at least 20A (20A x 12V = 240W). Since the control board only supports 15A, this setup requires an additional power module. Compatible with Chitu motherboards and other open 3D printer motherboards. Under normal cooling, this module is stable at I (Max) = 25A; the current used should not exceed 25A. Recommended for heated beds with 12V power supplies to prevent excessive current that could damage the control board. Compatible with Anet A8, A6, A2.
