12V and 24V can be used on MK2B (MK2A upgraded version)
LED and resistor soldered good
In the history of the best compatibility PCB thermal beds, support 12V 24V supply
1,12 V 24 power random access
2, double-sided, the other side is no wiring, heating uniformity, smooth printing
3, regardless of the positive and negative terminal, free wiring
Connects to 12V
Current 9.8A, as the temperature increases, the current drops to 8.8A (physical Tips: resistance becomes larger as the temperature rises)
Theoretical maximum current is less than 5A
If you use 24V, this time the current is very large, MOS tube severe fever, it is easy because the heat burned.
In addition, also consider the adequacy of power supply, power up to 576W of power is very expensive, if power shortage, it may affect the normal operation of the motor and other equipment.
Also note whether due to insufficient wire thick and hot, softened?
Latest version mk2b:
Relative latest version Mk2a, a major upgrade of 12V 24V dual power.
12V connection: a cable connected to one, the other a line while connected to 2,3.
24V connection: a cable connected to two, the other one wire to 3 (a floating not connected)
