  • Up to two plug-in options
  • Infrared communication port
  • THD even, odd and individual FFT harmonic analysis up to 50th order
  • Power and current demand calculation
  • On-board memory up to 2 MB
  • Programmable Min/Avg/Max and energy data logging
  • Event and alarm recording, waveform capture, waveform display, phasor diagrams, hystorical trending, time-of-use and more...

  • Switchboards, gensets, motor control centers, etc.
  • Power monitoring & control systems

Main features
  • 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, 8 energy counters available.
  • Total harmonic distortion for voltage and current up to the 31st order.

  • Two slots for optional AO plug-in boards (up to no. 2 analog outputs 0-20 or 4-20 mA).

  • The excellent graphical display performs clear graphical representations allowing an immediate comprehension of the measured parameters.

On-board memory
  • 128 kB 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.
  • 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).

  • Both RS232 and RS485 selectable by dip-switches.
  • Selectable MODBUS or A2 ASCII protocol.
  • Communication speed programmable up to 57600 bps.

Inputs & outputs
  • Two digital outputs for energy pulsing or for alarm tripping.
  • Up to 2 analog outputs 0-20 or 4-20 mA.

  • Real time clock with battery backup.
  • Calculation of capacitor bank value for PF compensation.
  • No. 1 programmable user page with 6 parameters selected among measured values.
  • Five alphanumeric character password to avoid unauthorized setup access.
  • Downloadable rmware via serial port.
