1. An uninterruptible power supply comprising:
- an I/O;
an output in electrical communication with the I/O; and
electronic circuitry coupled to the I/O and the output,wherein the electronic circuitry is adapted to, in a first mode of operation, receive AC power from the I/O and convert the AC power to DC power, and in a second mode of operation, receive DC power and provide AC power to the I/O, andwherein the electronic circuitry is further adapted to, in the first mode of operation, convert the DC power to AC power and provide the AC power at the output.

Abstract
At least one aspect is directed to an uninterruptible power supply including an I/O and an output in electrical communication with the I/O. The UPS also includes electronic circuitry which is adapted to, in a first mode of operation, receive power from the I/O and convert the AC power to DC power. The electronic circuitry is also adapted to, in a second mode of operation, receive DC power and to provide AC power to the I/O. The electronic circuit is further adapted to, in the first mode of operation, convert the DC power to AC power and to provide the AC power at the output.

15. A method of supplying power to two or more electrical loads, the method comprising acts of:
-
supplying, in a first mode of operation, power from a power source to an input of an uninterruptible power supply; supplying power from the power source to a first load in the first mode of operation; supplying power to a second load from an output of the uninterruptible power supply in the first mode of operation; and supplying, in a second mode of operation, power to the first load from the input of the uninterruptible power supply. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A UPS system for supplying power to two or more electrical loads, the system comprising:
-
an I/O adapted to connect to a first power source and a first load; an input adapted to connect to a second power source; an output adapted to connect to a second load; and means for receiving power from the first power source via the I/O during a first mode of operation, and supplying power from the second power source to the first load via the I/O during a second mode of operation, wherein the system is adapted to supply power from the output to the second load during both the first mode of operation and the second mode of operation. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
