ALLNET 4duino 3D Drucker zbh. Heizbett quadratisch 21,5cm 12V/24V RepRap Mendel

Parameters: MK2 Standard Version unterstützt 12V and 24V Stromversorgung Durchmesser 215MM Power ca. 144W

"Connection: 12 V/1A line, another thread after 2, 3, at the same time.By this time the amount of two wires resistance value is 1.0 ~ 1.2 ?, real power is 144W at 24V connection: a line 2, another thread after 3 (1 dangling don’t pick up), two lines of resistance value is 4.0 Ohm, actual power for 24 * 24/4 = 144 w.The new circuit, whether meet the 12 v or 24 v, the power is stable in 144 w.* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *Has good welding LED and resistorCompatibility in the history of the best PCB hot bed, support the 12 v and 24 v power supplyFeatures:1, 12 v power supply 24 randomly2, double panel, the other side without wiring, uniform heating, printing effect smoothRegardless of is negative 3, wiring, wiring at will* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *Test report:Pick up the 12 vCurrent is 9.8 A, as the temperature increases, the current dropped to 8.8 A (as the temperature rises, the little knowledge of the physics: resistance)After 24 V. The theory of maximum current is less than 5A. If you use 24 v, current is very large, MOS tube heat is serious, because of high temperature burned easily.In addition, consider whether the power supply enough, power 576 w power supply is very expensive, if the power is not enough, could affect the motor and other equipment to normal operation.Also, pay attention to whether the wire hot because of not enough thick, soft?The latest version mk2b:Relative to the latest version of Mk2a, mainly to upgrade the 12 v and 24 v power supply...Tested, 144 w can make hot bed temperature of 130 °, and fully meet user requirements."
