Term of the day : 'Inhibit'

A signal input to a power supply which will turn off the outputs (if the unit is fan cooled then this may also inhibit the fan). The signal has to be activated to make the outputs turn off, with nothing connected to the input, the power supply should operate. (Compare this with Enable).
