TH3D High Amp MOSFET V3 – Heated Bed or Hotend – 12V/24V Printers

Upgrade your heated bed to heat quicker* (if you have a stock external MOSFET or none at all) with our high amp MOSFET board. You can use this with heated beds or hotends (if you are wanting maximum protection). The main reason to use an external MOSFET like this one is to remove the high amp load from your bed off of the control board and put it onto this MOSFET module.

Compatible with PID regulation (used in our firmware). Works with any printer that runs on 12-24V on the board and heated bed. Also works with ESP, Arduino, and Raspberry Pi boards.

Technical Information

Rated up to 30A @ 3V-24V DC with fan cooling. 20A max load with no fan.

Large Screw Terminals for easy wire connection and works great with crimp ferrules.

Includes 12″ Control Wire – Connection from MOSFET to Printer Board

*Quicker heat-up times are based on testing in-house and customer feedback when using basic control boards or stock external MOSFETs. Not all printers will see quicker heat-up times. Other factors such as using PID or Bang-Bang regulation will also affect heating times on stock and our MOSFETs.

Installation, Wiring Diagram, & STLs for Mounting

STL files to mount to your printer (Universal and Creality Specific options are available) are included with purchase. All mounts use M3 screws to attach the MOSFET to the part (screws not included).

Part Fitment/Installation

This is a universal 3D printer part. That means it will work on almost any 3D printer (check your printer voltage and part voltage) with the correct mount for your specific machine. Thingiverse is a wonderful place to locate mounts and we also have printed parts in our shop for some universal parts.

It is up to you to determine and select a mount for your specific printer model (or design one) to install this part on your machine and wire it up to your machine (if applicable). You are welcome to Contact Us for recommendations for your particular printer model for mounting options that are available online if searching yourself does not yield any results.
