Description
• MK2B 3D printers Dual Power PCB Heated
• This heat bed has a dual power capability allowing it to be used with 12V or 24V power supply source        
• 2 Layer 35m Copper Red Solder mask Both Sides White Silkscreen Both Sides Copper Plated Holes
• Double panel, no wiring on the other side, even heating, smooth print
• 12V connection method: one wire connects 1 and the other wire connects 2 and 3 at the same  time ,At this time the resistance value of the two lines is 1.0 ~ 1.2, the actual power is 144W.
• 24V connection method: one wire is connected to 2 and the other wire is connected to 3 (1 is not  connected) the resistance value of the two lines is 4.0, actual power is 24 * 24/4 = 144W. The new version of the circuit, whether connected 12V or 24V, the power will stable at 144W
