INFORMATION

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.
