Max power output 'Fan' port UM1

Recommended Posts

Posted · Max power output 'Fan' port UM1

Hi guys,

It seems to be impossible to find the maximum power output at the fan port on an Ultimaker One. I want to install a second fan on the opposit side of the first one.

The standard fan seems to be 1.2 Watts, so I suppose one extra fan shouldn't do much harm. But first I want to make sure. :)

Thanks in advance!

An extra fan should be OK. Note that the fan output is actually 19V NOT 12V. The stock 12V fan is OK with this but other fans are not.

The output darlington transistor that drives the fan output is rated for a few amps so it can probably supply tens of watts. Another watt or two should be OK.
