● MK3 can choose between 12V and 24V working voltages, which is more practical.
● 1 layer 35μm (1oz base) copper
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 power 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 power is 24 * 24/4 = 144W.
The new version of the circuit, whether connected 12V, or 24V, the power will stable at 144W.
Current is 9.8A, as the temperature increases, the current drops to 8.8A (physical tips: resistance becomes larger as the temperature rises)
The theoretical maximum current is less than 5A
