Abstract: An apparatus and method for initializing electrical devices based on a voltage level. The voltage level may be modified to a particular setting based on the availability of power supply components, such as AC to DC rectifiers. Depending upon the availability of the power supply components, a control system may alter output voltage to a particular level. The components receiving power may be coupled to voltage dividers, where the voltage dividers are configured to modify an input voltage to cause or prevent the input voltage from rising above an initialization level for the particular component. The output voltage may be set by the control system such that a number of components that experience a voltage rise above an initialization threshold correspond to the number of available power supply components.
