Condition: New Supply Voltage: datasheet Dissipation Power: datasheet Operating Temperature: datasheet Model Number: title & photo Type: module Application: datasheet Types of: Other ICs batch number: 3d printer testing report: Then 12V Current 9.8A, with the temperature rise, the current dropped to 8.8A (physical knowledge: resistance increases with the temperature increases) Then 24V Theoretical maximum current is less than 5A If you use 24V, this time the current is very large, MOS tube heat serious, it is easy because of high temperature burned. In addition, consider whether the power supply is sufficient, power up to 576W power supply is very expensive, if the power supply is insufficient, may affect the motor and other equipment to normal operation. 2 layer, 35m copper Red Soldermask - both sides White Silkscreen - both sides Power Input: 12V or 24v 1.12V 24 power supply at will 2.double-sided, the other side without wiring,Heating evenly,Print is smooth 3.wiring, regardless of positive and negative, free wiring 4.12V connection: a line then 1, another line at the same time then 2,3 5.24V connection: a line connected 2, another line connected 3 (1 vacant not connected) 2 layer, 35m copper Red Soldermask - both sides White Silkscreen - both sides Power Input: 12V or 24v Copper plated holes colour:red Material:PCB board size:Dimensions 214mmx 214mm Laminate FR4 1.6 + -0.15mm Package Contents: 1*set board MK2b Only the above package content, other products are not included.
