MK2B Heatbed Heated Heat Bed 214 x 214 Dual Power 12/24V
1, 12V 24 power supply is free to connect
2, double panel, the other side has no wiring, heating evenly, smooth printing
3, the wiring is not divided into positive and negative, free wiring
Connected to 12V
The current is 9.8A. As the temperature rises, the current drops to 8.8A (physical knowledge: the resistance becomes larger as the temperature increases)
Connected to 24V
Theoretical maximum current is less than 5A
If 24V is used, the current is very large, and the MOS tube is hot and it is easy to burn because of the high temperature.
In addition, it is necessary to consider whether the power supply is sufficient. The power supply with a power of up to 576W is very expensive. If the power supply is insufficient, it may affect the normal operation of other equipment such as the motor.
Also pay attention to whether the wire is hot and soft because it is not thick enough?
Latest version mk2b:
Relative to the latest version of Mk2a, the main upgrade is 12V 24V dual power supply.
12V connection: one line is connected to 1, and the other line is connected to 2 and 3.
24V connection: one wire is connected to 2, and the other wire is connected to 3 (1 is not connected)
