Available Configurations

  • Single-phase and three-phase 3-wire or 4-wire unbalanced load operation.
  • Direct measurement up to 600 (750) VAC.
  • Programmable 1A / 5A current full scale.
  • True rms metering provides accurate measurement even for distorted waveform.
  • Fully bidirectional, four-quadrant readings. 10 energy counters are available, the apparent energy is splitted in four counters: import lagging, import leading, export lagging, export leading.
  • Volts, Amps, Power, PF, Frequency, Energy, Min/Max values, Demand, Harmonics, etc. The full version instrument provides more than 600 measured/calculated parameters and shows on the LCD more than 35 graphical pages.
  • Individual & total harmonic distortion for voltage and current up to the 50th order. The harmonic content is represented like even, odd and total.
  • Advanced waveform capture function. The instrument can store, after a trigger, up to 200 waves with a resolution from 16 to 128 samples (depending on the number of waveforms). The trigger can be programmed on a digital output change, on a set point crossing or the capture can be started from the keypad. The stored waweform is downloadable through the communication port.
On-board memory
  • 2 MB non-volatile memory for data storage.
  • Programmable start/stop time of recordings.
  • Wraparound or Fill (FIFO/Stack) selectable recording mode.
  • Min/Avg/Max logging every 1, 5, 10, 15, 30, 60 minutes, programmable up to 8 selectable parameters.
  • Total and daily energy consumption recording. The consumption of more than 300 days is recorded.
  • Time-of-Use (TOU) programmable data recording. The TOU function stores the energy consumption in different registers according the programmed time-scheme. A group of 200 registers gives the situation of the previous and current day, and of the previous and current month. This feature is designed to t different tariff structures, according to the number of TOU included in instrument:
    • 5 TOU: it is possible to program up to 120 daily tariff schedules containing up to 5 tariffs and 15 tariff changes. Each schedule can be assigned to the days of the week and months as requested. Up to 20 holidays can be assigned to the lowest tariff. Moreover, the holiday function can be enabled or disabled. A diagnostic algorithm checks and noti es any setup overlapping.
    • 4 TOU: it is possible to program up to 10 daily tariff schedules containing up to 4 tariffs and 8 tariff changes. Each schedule can be assigned to the days of the week and months as requested. Up to 20 holidays can be assigned to the lowest tariff. A diagnostic algorithm checks and noti es any setup overlapping.
  • In case of more than one electricity supplier, it is possible to start from the recorded demand values instead of the daily ones. Each value is recorded with date and time and can be exported for example, in .xls format. This allows to create a exible map that considers the different electricity suppliers. The DMD value is the AVG value (see programmable recordings).
  • Event, alarm and digital outputs ON/OFF recording. The instrument records the status change of 8 programmable set points, the digital outputs ON/OFF and the instrument supply ON/OFF. All the events are integrated by date and time reference.
  • Two slots for optional AO plug-in boards (up to no. 4 analog outputs 0-20 or 4-20 mA).
  • The compact DIN96 instrument allows to t the requirements of new installations as well as retro t applications.
  • The excellent graphical display performs clear graphical representations allowing an immediate comprehension of the measured parameters. The voltage and current waveforms, the harmonic spectrum and the phasor diagrams are displayed. Moreover 6 measured values can be represented as a graphical trend on the display. The scale of the trend can be selected between 15 min, 1 hour, 1 day and 1 month.
  • Both RS232 and RS485 selectable by dip-switches.
  • Selectable MODBUS or A2 ASCII protocol.
  • Communication speed programmable up to 57600 bps
  • Optional Pro bus interface.
