3D Printer High Power MOSFET 30A - for Heated Bed or Hotend

This is a high power MOSFET module specifically intended for 3D printers. The module can be connected to a heated bed or hotend connection and can handle a PWM signal.  

Specifications:

• Input voltage: 12-24V DC
• Maximum current: ~30A
• Signal voltage: 5-24V
• Possibility to connect the heated bed output signal of your 3D printer motherboard to this module (BED on the PCB)
• Possibility to control the module with a digital signal (SIG on the PCB)
• Has four 3.6mm holes for mounting
• Dimensions: See images

Figure 4 shows a connection diagram. The heated bed output signal from the motherboard is used to control the module. A 24VDC power supply is also used, this is sufficient to provide everything with power. Please note that the motherboard of the 3D Printer  can handle 24VDC as input voltage when using this power supply.

Note: Always check if the polarity is correct before applying voltage to the module.
