The three-phase four-wire multi-functional electric meter utilizes large-scale integrated circuits, digital sampling processing technology, and SMT technology. It features independent modulated infrared and dual RS485 interfaces. This meter boasts high reliability, high precision, wide measurement range, and long service life. Moreover, the three-phase four-wire multi-functional energy meter is widely used for measuring three-phase AC power in industrial and commercial settings.

Function characteristics of the multifunctional electricity meter

Energy Measurement: Capable of measuring active power in both forward and reverse directions, apparent power in both forward and reverse directions, reactive power in quadrants 1, 2, 3, and 4, as well as active and reactive power for phases A, B, and C. It can also set up selective addition or subtraction combinations of active and reactive power characteristics for forward and reverse active power and four quadrants of reactive power, generating combined active power, combined reactive power 1, and combined reactive power 2. It can store energy data for 12 settlement cycles.

  Time-of-Use Rates: The three-phase four-wire multi-functional electric energy meter can be set up with two sets of time zone schedules and two sets of daily time period plans, along with the switching times for each set (year, month, day, hour, minute); public holidays can be set, along with the dates and time period schedule numbers for each; weekly off days can be set, controlled by the characteristic words of the weekly off days, and the time period schedule numbers used on weekly off days can also be set.
