[RE-wrenches] 48 V DC temp sensing relay

[William Miller]

Drake:

I tried running 48 VDC muffin fans on battery voltage. They failed. I
switched to a Dc-Dc converter (12 or 24, can’t remember) from digi-key and
problem solved.

Point being battery voltage ranges may be too extreme for some components.
