Heated Bed Power Module MOSFET Expansion High Current Load Module With CableFeatures: Completely solves the issue of high power consumption and excessive load current for heated beds Operates stably under normal cooling conditions with a maximum current of 20A 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 allows 3D printers equipped with Chitu controller boards (rated for up to 15A) to handle higher currents, increasing the maximum current capacity up to 25A Based on power MOSFET technology, enabling PID control of the heated bed (unlike DC-DC relays, which typically do not support PID control)Specifications: Size: 6 x 5 x 3.1cm / 2.36 x 1.97 x 1.22 inches Mounting holes: 3.2mm diameter, compatible with M3 screws Distance between holes: 54 x 43mm High-performance MOSFET capable of handling higher current than standard RAMPS or typical 3D printer controllers Voltage: 12V–24V Maximum current with active cooling: 25A Operates stably under normal cooling with a maximum current of 25A; current must not exceed 25A during operation Package includes: 1 x MOSFET Expansion Module 1 x Cable
