Color: redSize: 214 mm x 214 mmPacking: bubble bag wrappedLaminate FR41.6 +/- 0.15 mm2 Layer, 35 micron copperRed thick - both sidesWhite silk print - both sidesPower input: 12V or 24VCopper plated holesOhm resistor between 1.0 and 1.212V connection: a cable is connected to 1, while the other connected to 2, 3 at the same time. At that time, the resistance of the two lines is 1.0 ~ 1.2?, the actual power is 144W.24V connection: a cable is connected to 2, while the other connected to 3 (1 unconnected ), the resistance of the two lines 4.0?, actual power is 24 x 24/4 = 144W.The new version circuit, whether it is connected 12V, or 24V, power is stable for 144W.Soldered LED and resistor The PCB heat bed with good compatibility, support 12V and 24V power supplyFeatures:1 12 V or 24 power random access2 Double-sided panel, no wiring the other side, heating uniformity, smooth printing effect3 Regardless of the positive and negative pole, free wiring connectionTest Report:When it is for 12V connection,current 9.8A, as the temperature increases, the current drops to 8.8A (physical knowledge: resistance becomes larger as the temperature rises)When it is for 24V connection, the theoretical maximum current is less than 5AThe latest version mk2b:Relative latest version Mk2a, a major upgrade of the 12V and 24V dual power.After testing, 144W allows heat bed temperature reaches 130 °C, fully meet user requirement.1 x Heat bedPacked in bubble bag
