@macpit69 said in permanent Power on OUT_0:

strange is that I can measure between GND and OUT0- 22.5 volts. But this seems to be okay.

To clarify that, the positive side has continuous power (via a fuse) and the negative side is switched to 0V / ground by a MOSFET to enable the heater, so both pins will be at or near the supply voltage with the heater output off.
