Heated bed power module features:

• Based on powerful MOSFET HA210NO6
• Dimensions: 60x50mm.
• Mounting holes: 3.2mm diameter, for M3 screws.
• Distance between holes: 54x43mm
• Very powerful MOSFET to withstand higher current than other 3D Printer controller can handle.
• Voltage: 12V-24V
• Maximum current with active cooling: 210A
• Current: 50-80A safe for prolonged times without active cooling.
• This module is based on power MOSFET and will allow PID control of the heated bed (DC-DC Relays usually do not allow this)
• This listing is for one power module for controlling 3D printer heated bed, it is also can be used to drive other non-inductive loads. If you plan to use silicone heater of large area heated bed, you most likely will overcome limitations for the current, that can handle your current 3d printer electronics. This control board will handle high current without even getting warm. Oversize MOSFET and overall very robust PCB design will allow for trouble free operation without active cooling
