This is the standard design of MK2B Dual Power PCB as described on reprap.org

- Heatbed with 3.2mm Aluminum Core. Print directly on the heatbed, no need for glass plate. It's a much lighter solution than PCB heatbed + glass, which makes it better for faster prints.
- Dual power supply. Operate at 12V or 24V. You can use thinner wires when operating at 24V.
- A central mounting hole on the front side to allow for three point mounting. This is much easier for bed leveling in comparison to 4 point mounting. First level the side with two holes and fix in place, then level the side with one hole.
- Large solder pads for multiple wires (ribbon cable) or a SMD pinhead connector can be mounted.
- Pads for SMD LED indicators

• Dimensions 214mm x 214mm
• 1 layer 35µm (1oz base) copper
• Resistance between 1.4 and 1.6 ohm for the 12V
• Resistance between 5.0 and 5.4 ohm for the 24V
• 100 degree Celsius possible for both 12V and 24V
• With 15V on the 12V terminals will maintain approx. 115 degree Celsius without regulation
• Running 24V on the 12V terminals will heatup the heatbed to 100 degree in only 2 minutes (Your printer controller will regulate the power to the heatbed in order to get your preset temperature.)
• 180 degree Celsius max. temperature

Kit includes:
- 1pcs MK2B Dual Power Heatbed PCB (More information about Heatbed PCB)

Note: Thermistor is no longer included see related products for these.

The board has positions to fit an SMD LED and resistor but they are not fitted or included.

Compatible with: RepRap, Mendel, Prusa and other various DIY 3D printers.
