Abstract
The power sensing device includes a power input interface in electrical communication with a current sensing circuit and a voltage sensing circuit. The current sensing circuit is connected to a load. The voltage sensing circuit is connected in parallel with the load. A metering integrated circuit and a micro-controller unit (MCU) are included. The metering integrated circuit receives a first analog signal indicating a load current value from the current sensing circuit, and a second analog signal indicating a load voltage value from the voltage sensing circuit. The metering integrated circuit converts first and second analog input signals to first and second digital signals, respectively, and generates the first and second digital signals as digital communication pulses to the MCU. A decoder circuit includes a communications port to send and receive data associated with a sensed current parameter and a sensed voltage parameter.
