MK3 21*21*3mm 12V/24V 120W Aluminum Heated Bed Plate for 3D Printer

Descriptions:● MK3 can choose between 12V and 24V working voltages, which is more practical.● 1 layer 35μm (1oz base) copper
● Resistance between 1.4 and 1.6 ohm for the 12V
Resistance between 5.0 and 5.4 ohm for the 24V
● 100 degree Celsius possible for both 12V and 24V
● With 15V on the 12V terminals will maintain approx. 115 degree Celsius without regulation
●  Running 24V on the 12V terminals will heatup the heatbed to 100 degree in only 2 minutes (Your printer controller will regulate the power to the heatbed in order to get your preset temperature.)
