Description:
This module is based on the Power MOSFET and allows PID control of heated beds (DC-DC relay normally does not permit this).
At least 20A (20X12 = 240W) means that your total power usage is 240W, if you use 12V power supply.
The controller board can only be set to 15A, so this setting will not work. You will need this extra power module to work it.
Normally, under cooling conditions, the module will find stable operation at I(Max) = 25A, current use must not exceed 25A.
This module is recommended if you use a bed with a 3D printer using a 12V power supply.
