3MM MK3 Aluminum Board PCB Heat Bed 214*214mm

Specifications: 1 layer 35μm copper Voltage: 12/24V Resistance: 1.4-1.6 Ohm at 12V 5.0-5.4 Ohm at 24V Max. Temp: 180° C Heating Time: 24V reaches 100° C in 2 minutes Dimensions: 215 x 215 x 3mm Weight: 363g Colour: Black with White Mask/Text MK3 can choose 12 v and 24 v two voltage, 12 V: one line thread cross 1, another cross 2, 3 24 V: one line thread cross 2, another cross 3 (1 don't need to pick up). The new circuit, whether meet the 12 v or 24 v, the power is stable.
