E51C2 Bi-Directional Compact and Energy Meter With Modbus Communication The meter shall be fully electronic with multi-line backlit LCD display showing measured parameters as well as alarm functions and pulse output. The power meter shall perform the following measurements: Total Real Energy (kWh) (a signed net sum of all energy imported and exported) Real Energy (kWh), imported (from the grid), exported (to the grid) for each phase and totals for all phases Reactive Energy (kVARh), both imported (from the grid) and exported (to the grid), by Quadrant, as defined by IEEE 1459-2000 Apparent Energy (kVAh), imported (from the grid), exported (to the grid), and signed net Net Present Demand for Real (kW), Reactive (kVAR) and Apparent (kVA) over a user-specified interval (block or sliding window) Maximum (Peak) Real (kW), Reactive (kVAR) and Apparent (kVA) Demand Intervals, both imported (from the grid) and exported (to the grid) Instantaneous Real (kW), Reactive (kVAR) and Apparent Power (kVA), by phase and in total Current (amps) for each phase and average of all phases Phase-to-phase voltage for each phase and average of all phase pairs Phase-to-neutral voltage for each phase pair and average of all phases Power factor for each phase and average of all phases AC frequency The power meter shall communicate all these measurements using the Modbus RTU protocol at speeds from 1200 to 38400 baud; odd, even, or no parity. The power meter shall also provide a separate pulse output (of total Real energy).
