Abstract: A system of one embodiment is disclosed that includes a load, a power supply, and a mechanism. The load is operable in a default mode and an alternate mode. The load has better performance in the default mode than in the alternate mode, and consumes less peak power in the alternate mode than in the default mode. The power supply is connectable to an external power source to provide voltage to at least the load. The mechanism causes the load to operate in the alternate mode upon detecting the voltage provided by the power supply dropping below a predetermined threshold level than a predetermined threshold number of times.

The power supply is connectable to an external power source to provide voltage to at least the load. The mechanism causes the load to operate in the alternate mode upon detecting the voltage provided by the power supply dropping below a predetermined threshold level more than a predetermined threshold number of times.

Abstract: A new and improved rectifier power supply operates in a low voltage mode of operation and a high voltage mode of operation without user intervention and includes an inrush current limiting device that is in circuit during a predetermined period of time during start up and bypassed during steady state operation in the low voltage mode of operation. In the high voltage mode of operation, when inrush current is reduced relative to the low voltage mode of operation, the inrush limiting device always remains in circuit. As there is no power loss associated with the inrush limiting device in the steady state low voltage mode of operation, the power supply has an improved efficiency and reliability and a reduced cost as it can be rated for continuous operation only in the high voltage mode of operation when the input current is lowest and device dissipation is least.
