An elevator system includes a primary source of electrical power; a power unit having a power supply, the power supply producing DC power from the primary source of electrical power. A rescue storage device provides power to the elevator system when the primary source of electrical power is unavailable. The rescue storage device is coupled to an output of the power supply to provide additional DC power with the DC power when the primary source of electrical power is available and an increased power requirement is present.
