    摘要: A system and method for supplying uninterruptible power include a housing, a power supply input, a power source equipment input, a powered device output, an alternative power supply, and a control module. The control module includes a comparator, a switch, and an injector. A PoE powered device connects to the powered device output by Ethernet cable, and power source equipment connects to the power source equipment input. The control module connects the power supply input, the power source equipment input, the powered device output, and the alternative power supply. The power source equipment is powered separate from the power supply input. When the comparator detects sufficient power from the power supply unit, the switch directs power from the power supply input to the powered device. When the comparator detects insufficient power from the power supply unit, the switch instantaneously directs power from the alternative power supply to the powered device.

    摘要: A system (10) and method for supplying uninterruptible power has active power negotiation and an extended range. The system includes a housing (12), a power supply input (14), a power source equipment input (16), a powered device output (18), an alternative power supply (20), and a control module (22). The control module (22) includes a comparator (36), a switch (38), a converter (40) and an injector (34). The injector includes a regulator (45) and power autonegotiation module (47). The injector actively manages the power to the powered device, even when the PoE available from older power source equipment differs from the PoE requirements of an updated powered device. There can also be an Ethernet switch (49) as a power source equipment extension between the powered device and the system. The Ethernet switch extends the range of the powered device from the system.
