Static electricity meter for three-phase four-wire networks. Allows direct (NEO3tdgr) or indirect (NEO3atdgr) measurement of active and reactive energy in four rate plans, switched by a built-in real-time clock. Universal meter for a wide range of applications.

  • Unidirectional, bidirectional or reverse active energy measurement
  • Two-quadrant or four-quadrant measurement of reactive energy
  • Measurement of instantaneous power, logging maximum power for a billing period
  • Recording load profile (configurable averaging period)
  • Measurement of power grid parameters
  • Manual and automatic ending of a billing period
  • Memory of 16 billing periods data
  • Real-time clock with a calendar to switch between four rate plans
  • Calendar allowing to define special days, permanent and movable holidays for 20 years forward
  • Communication via an optical port and serial port (RS-485 or RS-232)
  • Pulse output for active and reactive power
  • Extensive event logging
  • Dedicated LCD display, signalling proper connection of current circuit and voltage circuit and signalling the presence of voltage and current
  • Capability to connect an additional external power supply (230V AC/100-300V DC) for parameterisation/ readout of the measurement data if there in case of power outage
  • Separation of current and voltage circuits
  • KomPaf maintenance software (software protection dongle available as an option)
