ISKRA UMT 540 Multifunction Transducer & Analyzer
UMT 540 is intended for measuring and monitoring single-phase or three-phase electrical power network. It measures RMS value by means of fast sampling of voltage and current signals, which makes instrument suitable for acquisition of transient events. A built-in microcontroller calculates measurands (voltage, current, frequency, energy, power, power factor, THD phase angles, etc.) from the measured signals.
Features:
• Measurements of instantaneous values of more than 140 quantities (U, I, P, Q, S, PF, PA, f, j , THD, MD, energy, energy cost by tariffs, etc.)
• Power accuracy class 0.2
• Harmonic analysis of phase, phase-to-phase voltages and currents up to 31st harmonic
• Measurements of 40 minimal and maximal values in different time periods
• 32 adjustable alarms
• Frequency range from 16 Hz to 400 Hz
• RS 232/RS 485 communication up to 115,200 bit/s or Ethernet communication or USB communication or Ethernet and USB communication simultaneously
• MODBUS and DNP3 communication protocols
• Remote display connection
• Up to 4 inputs or outputs (analogue outputs, pulse outputs, alarm outputs, tariff inputs)
• Additional communication port (COM2)
• Universal power supply (two voltage ranges)
• Automatic range of nominal current and voltage (max. 12.5 A and 600 VL-N)
• Adjustable tariff clock, display of electric energy consumption in selected currency
• Housing for DIN rail mounting
• User-friendly PC MiQen software
