EA52

Single-phase static electricity meter. Intended for measuring active energy in four time-based plans, switched by a built-in real-time clock. It is a reliable and proven solution, preferred due to its broad functionality and compact casing.

  • Unidirectional, bidirectional or reverse active energy measurement
  • Measurement of instantaneous power
  • Measurement of phase voltage and current
  • Recording maximum power and excessive power for a billing period
  • Recording load profile (configurable averaging period)
  • Manual, automatic and remote ending of a billing period
  • Memory of 16 billing periods
  • 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
  • An option to activate one of the 5 plans and set the time using a button with a seal
  • Communication via an optical port and serial port (RS-485 or RS-232)
  • Pulse output for active power
  • Extensive event logging
  • Immunity to magnetic field
  • Dedicated LCD display, signalling proper connection of current circuit and voltage circuit and signalling
  • the presence of voltage and current
  • Possibility to read data from the display in case of power failure
  • Controlled by KomPaf software (software protection dongle available as an option)
