mosfet controller board to extrude

Postby planetech3D » Wed Aug 07, 2019 10:22 am

Hello,
I would like to know about the controller board to extrude the mosfet for the fans "7R0 60 PEm 1602 b7 8967" can provide up to what current in 12v
I would need 700mA constant and 1.3A peak.
I did not find the data sheet on this precise value of mosfet.
Thanks for your feedback

This Mosfet should be able to support 700mA.

Actually it functions on controlled outputs.
Knows when power limit, as soon as the motor forces a little LED lighting decreases brightness.
On the permanent 12vdc with the motor the voltage drops 10.3vdc to 12.3vdc places without motor.

The 12vdc control part of the control board is too limited in power, it is not very reassuring to use in the long time.

Would you like to advise more information of the motor you want to add?
We can only guarantee that the peek current here can support can only be around 1A.

The 12v supply to that board is limited by a 12v regulator on the main board and is limited to 3A but this regulator supplies the extruder fan, part fans and the LED lights - you don't have a lot of room when you add everything up. The FETs are NOT the bottle neck.
