摘要： An intelligent electronic device (IED) having a gain control unit adapted to selectively regulate operating ranges of output signals of a sensing circuit of the device is described. In one embodiment, the IED is a digital electric power and energy meter, which operating ranges for supply voltages and supply currents of electrical services may be adjusted to match pre-determined ranges for input signals of a data acquisition system or a data processing module of the meter.

摘要： A device and method are provided for managing flash memory of an intelligent electronic device (IED) to maximize the IED life. The IED includes at least one sensor for sensing at least one electrical parameter distributed to a load. At least one analog-to-digital converter is coupled to the at least one sensor for converting an analog signal output from the at least one sensor to digital data. A processing unit is coupled to the at least one analog-to-digital converter to receive the digital data and store the digital data in a memory. The memory includes sectors configured to store the digital data. The processing unit stores the digital data in each of the sectors and equalizes usage of each sector over time by equalizing a number of erases for each of the sectors over time.
