I am in the process of upgrading my printer to run on 24V, but I have a question regarding the 16V, 11A polyfuse. Why is it rated at 16V? I can't see there ever being anything near 16V dropping across the fuse as it should be conducting with very low resistance. Using the datasheet specifications, when conducting 11A of current with a maximum resistance of 0.0089 ohms, that's only 0.09V dropped by the fuse. Using a 24V bed wouldn't draw that much current anyway. I understand that I need to change it, especially having read the reports on here about them catching fire and I will remove it and use a real fuse in it's place. I would just like to understand why.
Thanks :)
