MK2B Heat Bed Heatbed For 3D Printer RepRap Mendel

MK2B Heat Bed Heatbed For 3D Printer RepRap Mendel








Feature:
12V, 24V .
Double-sided, the side is no wiring, heating uniformity, smooth printing.
Regardless of the positive and negative terminal, you can free wiring.

Description:
Dimensions: 214 x 214 mm
Laminate FR4: 1.6+-0.15 mm
2 layer, 35μm copper
Red soldermask: Both sides
White silkscreen: Both sides
input: 12V and 24v
Copper plated holes
Resistance between 1.0 and 1.2

Connection:
12V connection: One cable connected to one, another cable connected to a wire 2,3 in the same time.
At this time the resistance value of the two lines is 1.0 ~ 1.2Ω, the actual is 144W.

24V connection: One cable connection 2, another line connected to 3 (1 unconnected), the resistance value of the two lines is 4.0Ω, actual is 24 * 24/4 = 144W.
The new version of the circuit, whether connected 12V, or 24V, the will stable at 144W.

report:
12V connection:
Current is 9.8A, as the temperature increases, the current drops to 8.8A (physical tips: resistance becomes larger as the temperature rises)
24V connection:
The theoretical maximum current is less than 5A

Note:
The LED and resistor are soldered, good compatibility, 12V, 24V .
If you use 24V, this time the current is very large, MOS tube heat seriously, it is easy burned because of the high temperature.
In addition, also consider the adequacy of supply, up to 576W of is very expensive, if shortage may affect the normal operation of such as motor.
Also note that because of the wire is not enough thick and cause burning hot and .

Package included:
1 x Heated Bed
