Frequently asked questions
What power supply does this heated bed need?
It is rated for 12 V and 90 W. At 12 V that is roughly 7.5 A at full power, so the power supply and wiring must handle that current. Many builders drive it through a MOSFET controlled by the board.
How is the thermistor connected?
The bed comes with a 100K thermistor lead. Connect it to the thermistor input for the bed on your controller board and set the firmware to a 100K thermistor type.
