  • 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

Product Description

Mosfet

BTMOS-V2.0 is a new module to optimize and upgrade the power expansion module of old heat bed,

which can solve the problem of high-power hot bed and serious heating.

BTMOS-V2.0 hot bed power expansion module, which can be connected with high power hot bed,

withstanding larger power, convenient for machine use while reducing the danger caused by serious heating.

Easy Connector

Positive and Negative connection

excellent heat dissipation

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

How Mosfet connect with those 3D printer part

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.

Customers are mixed about the heat of the cutting tools. Some mention that it handles heating up their bed without any issues, has great dissipation of heat, and does not even get warm. Others say that it starts to heat up on its own and that heavier use causes it to overheat and short out.

"...I got it installed and it worked like a dream, more consistent bed temperatures than before and have had 0 issues since installing it." Read more

"...Heating isn't directly affected, but you can run your bed heater off of a different power supply or a different voltage with this (the big win)." 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

A quick installation for a peace of mind.

A quick installation for a peace of mind.
It was a breeze to install this cute little MOSFET, for me it's just for the peace of mind because I installed this on my Anet A8 which is brand new. I can't tell if my Anet A8's mother board would fry without it. For the cabling, I reuse some leftover 16AWG wire taken from the ceiling fan / light to connect from the MOSFET's DC power to the printer's A/D power supply DC output. I did not connect from the MOSFET's DC ports to the motherboard's DC ports although it's like right next to it since I don't want the MOSFET to tap power from the motherboard, it's not recommended anyway. My 16AWG wires go underneath the printer to the other side where the A/D power supply sits (black wire to DC+, white to Ground or COM, it's kind of a detour to get DC power but it's a good detour.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.

4.0 out of 5 stars It works like a champ. Make sure you add an in-line fuse Just in case of a failure though.
Reviewed in the United States on October 4, 2017
Purchased this to heat up my 250mm x 250mm heated bed instead of having the bed heat up thru the main board. It was pulling too much current thru the main board, so I installed this to take the load off the board. It works like a champ. Setup required some Youtube searching.

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.
