BIQU Heat Bed Power Module Expansion Hot Bed MOS Tube for 3D Printer
- A general add-on heated bed power expansion module for 3D printer
- Completely solve the hot bed power is too large and the load current issue. It can work with the Anet A8
- With this addon module to your 3D printer motherboard you can lead the maximum current up to 15A
- Under the premise of normal heat dissipation, this module can work steadily under the condition of I(Max)=15A. Don't exceed 15A during the process.)
- If you intend to use heated bed with your 3D printer that uses a 12V power supply, then this module is recommended, else it may cause excessive current during times which may burn the connectors on the controller board, According to the thermal power of the bed, please choose the appropriate power supply, with sufficient margin. If it is large power heated, we suggest 24V power supply, under the same power requirements, current is less than 12 v

|
---|---|---|
it come with specified connection wiring and terminal connector with a nice touch ,greatly Convenient to connect with |
When you connect power supply cable, you need to pay attention to distinguish the positive and negative polarity of the power supply,and do not reverse the connection of the cable to avoid burning the module and causing unnecessary losses , DCIN: “+” connect the power positive electrode: “-”connect the power negative |
In order to achieve excellent ability of the heat dissipation, we give a lot of small holes on the Mosfet PCB Board |
The Mosfet connect with Ramps 1.6 control Board, 12864 LCD also with MK2B heatbed, When BTMOS V2.0 connect with Power Supply ,it need to Emphasize the Positive and Negative connection,it don't need to Distinguish the"+","-" cable, while it connect with Heatbed. Besides,our Mosfet Support to 12V&24V power supply, When the hot bed power is less than 180W, 12V power supply can be used; when the hot bed power is
more than 180W and less than 360W, it is recommended to use 24V power supply.

Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers like the performance, ease of installation, and value of the MOSFET. For example, they mention that it works great, it's easy to wire in, and it'll take a load off the main board. That said, opinions are mixed on heat, quality, and safety.

"...So far, no indication of excessive heat, at all. When heating for ABS, I use 110C for the print-bed...." Read more
Customers are mixed about the quality of the cutting tools. Some mention that the build quality is great, nice and solid, with good and solid solder points. However, others say that they have received two faulty mosfets and the connector terminals had a complete meltdown. The components are not rated to proper temp spec, making the product highly unreliable.

"Works fine when wired correctly. Quality is lacking. Needs instructions...." Read more
Customers are mixed about the safety of the cutting tools. Some mention that it makes their printer less of a fire hazard by taking the power load off the motherboard. They say it's a great addition for your 3D printer and prevents burnouts of the control board. However, others say that they are very dangerous and not as safe as you might think.
"...This results in not burning out your control board and allows you to swap out your heater for a different voltage (while still controlling it)...." Read more
"...These are a waste of time and money.They are dangerous if they are faulty of defective, because they can push current even when you are not..." Read more
"...They are easy to install and they made my printer less of a fire hazard by taking the power load off the main board." Read more
"...It was hot to the point that it was a definite fire hazard and I would absolutely not recommend this to anyone...." Read more

There was a problem filtering reviews right now. Please try again later.
I was happy that the installation worked the first time around. I used a printable mount I found on thingiverse to mount this board into the control box. I have about 50+ hours of printing time since the install and have seen no problems yet. For the price, and if everyone suggests this mod, I recommend you do it too. It took me about an hour or less to install and reassemble everything, and 2 hours of google image search to find enough install pics that I was comfortable enough with to do it without fear of frying something. My electrical skills are hobby level at best. I can solder, but would rather not. Pleased I didn’t have to. It would be nice to include a link to a more detailed installation guide. There are several out there but nothing “great”. I suppose since every printer is a little different, this might be a challenge, but I’m sure someone could whip something up that was decent with some close up pics for those people who don’t know jack about electronics.
No Instructions included, so here is a summary:
1. Remove basically all ouside screws for your Wanhaoi3 / MonoPrice Maker Select VIII control box.
2. Take pictures of existing board wiring.
3. Unscrew two large 12/14GA wires on the board labeled "hot bed".
4. Screw these two wires into the new mosfet board labled "hot bed".
5. Connect the small jumper wires (white) to the control board where you just removed the two wires and screw them down. Note the polarity on each board. Match (+) to (+) and (-) to (-).
6. FInd 2x 6-8" pieces of 12 or 14 AWG wire. Most cheap extension cords are 16AWG (too thin). Your local home depot / menards / ace will have this as cut-to-length.
7. Run one of the 6" wires to the power supply (+), screw in; and the other side to the (+) DC IN on the new mosfet board. Repeat for the negative wire (-) to (-).
8. Many people use velcro to secure the new board to the top of the control box. Others print off a holder from thingiverse.
9. Put everything back together.
10. When complete, you'll see a blue light activate for signal from inside the box when the bed heater is activated by the control board.
When the printer is turned On, the Red diode D1 (next to the HOTBED port) is turned On to indicate it's up and running. When the printer is heating up the Hotbed, the blue diode D2 next to the Control In port is turned On, the attached picture was taken when I manually selected the Quick Settings -> Preheat PLA. When the Hotbed is activated by the computer then D2 is turned on and off when the software needs it. That's about all I can tell if the MOSFET unit is working or not, the Hotbed went up to 190deg before and after the installation anyway.
Would I recommend it? Yes, if anything it's like buying a cheap insurance for this printer. I attach a few pictures showing how I attached it using the bottom left screw from the motherboard.
Have fun with this little project.
p.s. This MOSFET is scheduled on Today's Deals, hope you catch this deal.

Pros:
Easy wiring setup after I found instructions
Board is black and matches my current board.
Supports my 10 AWG wire
Doesn't need to be actively cooled
Cons:
Needed to find setup instructions
Needed to find my own mount (Me being picky, didn't count against product)
Other Thoughts:
Installed on an FLSUN Cube. Added a Dedicated PSU and upgraded the heated bed / PSU wires to 10 AWG ones to power the heated bed since the bed was that large and it drew that much current. Custom designed a mount for the board and the heated bed power expansion module. See attached photos for details!
Edit 12/16/2019
MOSFET Finally gave out after 2 years of regular use. Failed in the closed position, with the bed getting power. Not bad for a few dollar investment. With that being said, make sure that you have thermal runaway protection set up in your firmware and solder an in-line fuse for extra protection. This MOSFET got HOT (180C at least as it melted my mount) with full-blast current running thru it. So did my 10 AWG wires too. If it wasn't for my thermal runaway protection, I'm pretty sure I would have been looking at a fire, for sure.
