sold: 2


Name: 3D printer PCB reprap Heatbed MK2b product
Color: Black
Weight: 180g
Advantage of this product:
The whole process of 1 gold, the whole plate, the cost is much higher than hasl!
2, the whole board after optical circuit, open circuit detection.
3, such as the need to support the thermal and electrical wires, please buy the temperature measurement set”
Technical support and guarantee:
1, and the official Wiki product http://reprap.org/wiki/PCB_Heatbed compatible!

MK2B is more than the MK2A, features on the support of multi 24V voltage, MK2B is currently the official 24V version of the latest product on the machine. The whole system under 24V, can be used for more of the stepper motor, and a smaller loss. Is also a future development direction of 3D printers. Relative to the latest version of Mk2a, the main upgrade of the 24V 12V dual power supply.
12V connection method: a line of 1, another line at the same time, 2, 3.
24V connection method: a line of 2, another line of 3 (1 left vacant).
The new version of the circuit, whether it is 24V, or 12V, power supply stability.
1, 12V 24 power are compatible.
2, double sided board, the other side has no wiring, heating uniform, printing effect is smooth.
3, the wiring is not positive and negative pole, free wiring.
Test report:
12V, as the temperature increases, the current drops (physical knowledge: resistance increases with the temperature).
24V, the maximum current is less than 5A.
2 layer as 214mmx 214mm laminate FR4 1.6+-0.15mm, 35 mu m copper golden version red Soldermask – both sides white Silkscreen – both sides power input: 12V or 24V copper plated holes
