A system for limiting AC inrush current to a power supply. The system
comprises first, second, and third windings magnetically coupled to a
core of a transformer of the power supply. The system also comprises a
first low-voltage contactor and a second low-voltage contactor. The
system further comprises a first low-voltage impedance element connected
between the first low-voltage contactor and the first winding, a second
low-voltage impedance element connected between the second low-voltage
contactor and the first winding, a third low-voltage impedance element
connected between the first low-voltage contactor and the second winding,
and a fourth low-voltage impedance element connected between the second
low-voltage contactor and the second winding.
