Description: Completely solve too large heated bed power and load current problems Additional heating bed power supply expansion module This plug-in module on your 3D printer board can make the maximum current up to 25A Help 3D printer equip with a controller board (maximum 15A), more powerful When in normal cooling condition, it works at I (Max) = 25A current, no more than 25A Specification: Size: approx. 60 x 50mm/2.36 x 1.97" Color: black Maximum current: 25A (enhanced heat dissipation) Package Includes: 1 x Heated Bed Power Module 1 x Signal Cable Note: If a 3D printer is intended to use a 12V power supply to use heated bed module, then this module is recommended. Otherwise it will cause too much current on control panel. Depending on heated bed's thermal power, please choose appropriate power supply. If it is high-power heating, we recommend 24V power supply
