摘要： The present disclosure describes configurations for current shunt sensors and current shunt sensor assemblies having improved electromagnetic cross-talk rejection that can be used in single-phase/split-phase and poly-phase power metering applications. Some embodiments of the current shunt sensors and current shunt sensor assemblies reduce the need for a shielding material around current shunt sensors in single-phase/split-phase and poly-phase power metering applications. Some embodiments of the current shunt sensors achieve improved electromagnetic cross-talk rejection through a substantially symmetrical arrangement of component parts along the primary path of current flow. Some embodiments of the current shunt sensors achieve improved electromagnetic cross-talk rejection by symmetrical configurations that, in operation, induce complementary parasitic currents or voltages that substantially cancel each other out and do not substantially affect primary current flow through the current shunt sensor.

摘要： A power offload network has a node for receiving at least one supply V1. The power offload network includes at least one switch and a power offload element providing a supply drop of VR. The switch is configurable for selecting a linefeed supply level from the set including {V1, V1−VR}. A subscriber line interface circuit receives the selected linefeed supply level for driving a subscriber line.
