Heated Bed Power Module MOSFET Expansion High Current Load Module With Cable Features: Completely solves the issue of high power and excessive load current for heated beds Operates stably under normal cooling conditions with a maximum current of 20A The working current must not exceed 20A during operation Recommended for applications requiring 15A or higher For example, if your total power requirement is 240W with a 12V power supply, a current of at least 20A is required (20A × 12V = 240W) This high-power module enables 3D printers equipped with Chitu controller boards (rated up to 15A) to handle higher currents, increasing the maximum current capacity up to 25A Built using a power MOSFET design that supports PID control for heated bed temperature regulation (unlike standard DC-DC relays which typically do not support PID) Specifications: Dimensions: 6 x 5 x 3.1 cm / 2.36 x 1.97 x 1.22 inches Mounting holes: 3.2 mm diameter, compatible with M3 screws Hole spacing: 54 x 43 mm High-performance MOSFET capable of handling higher current than standard RAMPS or typical 3D printer controllers Operating voltage: 12V–24V Maximum current with active cooling: 210A Stable operation up to 25A under proper cooling; operating current must not exceed 25A Package Includes: 1 x MOSFET Expansion Module 1 x Cable
