DESCRIPTION

Three-phase power analyzer (balanced and unbalanced networks), assembly on panels or DIN rails, with a graphical display, with 4-quadrant measurement.

Other features include:

  • Class 0.2 or 0.5 power and energy
  • Measurement of power quality events (guaranteeing the power supply of the unit by means of a UPS system, battery, etc.)
  • Current measurement .../5 or .../1 A
  • Measurement of the neutral current with a transformer
  • Rating of consumed and generated energy (up to 9 tariffs)
  • RS-485 Modbus/RTU communication
  • Possibility of expansion (up to 3 modules)
  • Backlit VGA graphic screen
  • Instantly shows electrical parameters, maximum and minimum values with date and time
  • Consumed and generated energy meter up to 100 GW·h
  • Universal power supply as standard
  • With ITF technology: galvanic insulation protection

APPLICATIONS

  • Control application for general distribution switchboards and low-, medium- and high-voltage connection points
  • Alarm station, featuring voltage-free digital inputs
  • Submetering station: impulse meter for other services (gas, water, steam etc.) via the digital inputs
  • Measurement transducer: possibility of associating instantaneous parameters with one of the available analogue outputs (0 to 20 mA / 4 to 20 mA)
  • Unit for recording the instantaneous, maximum and minimum parameters, with date and time, via the memory expansion card
  • Power quality analyzer: Harmonic decomposition, up to the 50th order harmonic, asymmetries, flicker, unbalances, overvoltages, gaps, interruptions, etc.
