Definitions for "Supply Voltage"
units + Volts. The range of power required to maintain proper operation of a photoelectric control, proximity sensor or control base. The difference in potential (or range of difference in potential) necessary to operate the unit.
The voltage, usually direct, applied by an external source to the circuit of an electrode.
The DC input voltage necessary for oscillator operation. Currently 5 VDC is commonly used, with 3.3 VDC being used in portable equipment.
