Term of the day : 'Enable'

A signal input to a power supply which will turn on the outputs (if the unit is fan cooled then this may also enable the fan). The signal has to be activated to make the outputs turn on. With nothing connected to the input, the power supply should not operate. (Compare this with Inhibit).
