12V connection: a cable connected to one another while connected to a wire 2,3 .This amount of resistance when the value of the two lines 1.0 ~ 1.2, the actual power is 144W. 24V connection: a cable connection 2 , in addition to a cable connection 3 ( 1 left unconnected ) ,Two lines of the resistance value of 4.0, the actual power is 24 * 24/4 = 144W. The new version of the circuit , whether connected 12V, or 24V, Power stable at 144W. ******************************************LED and resistor soldered goodThe best history of PCB hot bed compatibility , support for 12V 24V Power Features :1,12 V 24 power random access2 , double-sided , the other side there is no wiring ,Uniform heating,Smooth printing3 , regardless of the positive and negative terminal , free wiring ******************************************Test Report:12V connectionCurrent 9.8A, as the temperature increases , the current drops to 8.8A ( physical Tidbits: resistance becomes larger as the temperature rises ) 24V connectionThe theoretical maximum current is less than 5A The official introduction ;reprap.org/wiki/Heated_Bed If you use 24V, this time the current is very large , MOS tube heat seriously , it is easy because the high temperature burn .In addition, also consider the adequacy of power supply , power up to 576W of power is very expensive if power shortage may affect the normal operation of other equipment such as motor .Also note that because the wire is not enough thick and hot, softened ? The latest version mk2b:Relative latest version Mk2a, a major upgrade of the 12V 24V dual power .. . After testing , 144W allows hot bed temperature reaches 130 , fully meet user needs.
