Iskra Doo MC740 S SFUNC, Panel Mount Measuring Center 3 Phase, Class 0.5 50-500VAC L-L 50/60Hz Measurement, 240VAC Supply, USB Comms, w/ Supercap
- Smart Meter
- Automatic range of nominal current up to 12.5 A (Includes 5A/1A CT Input) and nominal voltage up to 750 V L-N
- Adjustable tariff clock, display of electric energy consumption in optional currency
- Optional RS 232/RS 485 communication up to 115,200 bit/s or Ethernet communication
Usage
The meter 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
- 32 adjustable alarms
- Wide frequency range from 16 Hz to 400 Hz
- RS 232/RS 485 communication up to 115,200 bit/s or Ethernet communication
- MODBUS and DNP3 communication protocol
- MMC memory card for setting and upgrading the meter
- Up to 4 inputs or outputs (analogue outputs, pulse outputs, alarm outputs, tariff inputs)
- 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
- 128 samples in one period
- Measurement of THD on Current or Voltage from 0 to 400%
