The POwer Quality Analyser is intended for measuring, analysing and monitoring single-phase or three-phase electrical power network. The meter records TRMS value according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates measurands (voltage, current, frequency, energy, power, power factor, phase angles, etc.) from the measured signals.
Features :
- Measurement of instantaneous values of more than 140 quantities (U, I, P, Q, S, PF, PA, f, f, MD, energy, energy price by tariffs, etc.).
-
Accuracy class 0.5 or 0.2 (on demand)
- Measurement of 40 minimal and maximal values in different time periods
- Optional 32 adjustable alarms
- Optional wide frequency range from 16 Hz to 400 Hz
- Optional RS 232/RS 485 communication up to 115,200 bit/s or Ethernet communication
- Optional MODBUS and DNP3 communication protocol
- MMC memory card for setting and upgrading the meter
- Up to 20 inputs or outputs (analogue outputs, pulse outputs, alarm outputs, tariff inputs)
- 1 Status and 1 Relay Output
- Universal or AC power supply
- Graphic LCD 128 x 64 dots with illumination
- Automatic range of nominal current up to 5 A and nominal voltage up to 750 V
- Adjustable tariff clock, display of electric energy consumption in optional currency
- Multilingual support
- User-friendly PC MiQen software
