EQUS

Multipurpose electricity meter for three-phase four-wire networks, with extended functionality. It allows direct measurement of active and reactive energy in multi-rate prepayment metering mode or in a fully autonomous credit mode. Interchangeable communication modules and a built-in contactor make the device a perfect founda­tion for Smart Metering systems.

  • Bidirectional and reverse measurement of active and reactive energy
  • Measurement of power grid parameters: effective current and voltage, frequency, power factor
  • Measurement of instantaneous power and maximum power
  • Load profile logging
  • Built-in contactor which allows disconnection of current circuits
  • Operating mode: prepayment, credit or switched prepayment-credit
  • Advanced prepayment functions
  • Manual or automatic ending of a billing period
  • Memory of at least 21 billing periods data
  • Real-time clock managing two switchable complex calendars
  • Calendars supporting 16 time zones and allowing to define any number of special days and permanent holidays, and 240 movable holidays
  • Current and power limiting features
  • Event logging
  • Optical port and built-in communication port: serial (RS-485 or RS-232), M-Bus slave, M-Bus concentrator
  • Removable communication module: PLC, GSM, RS-232/RS-485, LAN, SRD radio or other
  • TV remote control via infrared port
  • LCD display
  • Measurement data can be read from the display (and by optical connection if powered by a replaceable AA 3.6 V battery) in the event of power failure
