Enclosure Heater on Duex2

Hi guys,

I want to mount a Enclosure heater for my 3D printer and was wondering if the Duex2 Expansion board is able to power this through the extruder heaters.

I have read somewhere that the Duet Wifi is able to go upto about 9Amps for the extruder heaters but couldn't find much information for the Duex2 boards.

Enclosure heater that I am using: [www.ebay.co.uk]

So the heater is 24V at 150W - which would be about 6.25Amps, can anyone confirm if this is okay to power through the extruder heaters on the Duex2 expansions board.

We normally say 5A maximum for Duet heater outputs, however the mosfets and connectors can handle more than that. So I think 6.25A should be OK. The weakest point is probably the vias connecting the mosfet source terminal to the ground plane.
