Abstract: An intelligent power supply system includes a transformer and at least one gate unit. The transformer is configured to electrically connect to a higher voltage power source and to convert the higher voltage to a first reduced voltage. The transformer provides the first reduced voltage via a first output. The gate unit is operable to receive the first output and provide a second output at a second reduced voltage. At least one low voltage electrical device is electrically connectable to the second output. The transformer may electrically connect to a higher voltage power source at a first location, with the gate unit disposed at a second location remote from the first location, whereby the higher voltage power source is not at or near the second location, which may comprise a display location with various electrically powered display devices that are powered by the reduced voltage provided by the gate unit.
