Features: Very powerful to withstand higher current than normal RAMPS or other 3D Printer controller can handle Application: This high power module is a general add-on heated bed power expansion module for 3D printer. It can work with the A8. The heat bed power module can be used in both Chitu motherboard and other open 3D printer motherboards. 25A MAXIMUM CURRENT: This high power module helps your 3D printer equipped with the Chitu controller board capable of 15A become even more powerful. With this add-on module to board leads the maximum current up to 25A. When using heated bed 3D printer for 12V power supply which may cause excessive current during times, with this module, it can well protecting the connectors on the controller board from burning.
