Feature: 1. The hot bed power module can be used for Chitu motherboards and other open 3D printer motherboards 2. This high-power module is a conventional additional heating bed power expansion module for 3D printers 3. Can be used with for Anet A8. When using a heated bed 3D printer to provide 12V power, sometimes causes excessive current 4. Using this module can well protect the connector on the controller board from being burned. Completely solve the problem of excessive heating power and large load current 5. High-power expansion module of the hot bed, the appearance is small and atmospheric, the unique design of the snowflake heat sink, the heat dissipation is more powerful Specification: Item Type: 3D Printer Hot Bed Module Material: PCB Purpose: 3D printer Product Description: Hot bed high-power expansion module, compact appearance, unique snowflake heat sink design, more powerful heat dissipation, to solve the problem of excessive heating bed power and current load, this module is under normal heat dissipation, and the measured I (maximal) = 30A, it can work stably for a long time. During use, the current should not exceed 30A.. Package List: 2 x Module8 x Power Cord8 x Power Cord Top1 x Signal Line Note: When using a hot bed with a power greater than 150W, please connect an external high‑power module.
