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% Specification Iskra Doo Part Number MC740 S SFUNC Functions Power Quality Meter, Energy Meter, Power Transducer, Network Analyser Supply Voltage 240VAC < 5VA 50/60Hz Nominal Measurement Range 50-500VAC L-L, 5 Amp Maximum Measurement Range 750V L-N, 12.5 Amp Alarm N/A (Optional 4 Relays, 32 Alarms, 4 Groups) Analogue Output N/A (Optional 4 x 20mA) Digital Input N/A (Optional 4 x 230VAC/DC,75..130VAC/DC..5..48VAC/DC) Pulse Output N/A (Optional) Pulse Input N/A (Optional) Bistable Switch/Latching Relay Alarm N/A (Optional) Status (Watchdog) Output N/A (Optional) Tariff Input N/A (Optional 4 x 230VAC/DC,75..130VAC/DC..5..48VAC/DC) Accuracy Class 0.5 (I,U,F,PF,θ,THD) (Class 0.2 Optional) Class 1(Active), Class 2 (Reactive) Battery Backup Supercap Real Time Clock 1min/month (30ppm) Internal Memory 8MB MMC up to 2GB Isolation 3.7kV Ethernet RJ45 10/100Mbit/s USB Yes (2400-115200 b/s) RS232/RS485 N/A (optional 2400-115200 b/s) Weight 600g Certification UL, CSA, ROHS Factory Pack Qty 1 EU Directives Degree on electrical equipment designed for use within certain voltage limits URLRS 53/00 (Directive 73/23/EEC on low voltage): SIST EN 61010-1:2002 Safety Requirement for electrical equipment for measurement, control and laboratory use, part1 : general requirement Decree on electromagnetic Compatibility (EMC) URLRS 61/00 (Directive 89/336/EEC on electromagnetic compatibility): SIST EN 61036 item 4.5: 1998 Meters for active energy (class 1 and 2) Safety Protection Class II 600V rms, installation category II 300V rms, installation category III Pollution Degree 2 in compliance with SIST EN 61010-1:2002 Enclosure Material PC/ABS non combustable-self-extinguishability, complying with UL 94 V-0 Enclosure Protection IP52 (IP00 for terminals) in compliance with SIST EN 60529:1997 Resistance to HF Interference Immunity to radiated electrostatic fields IEC/EN 61000-4-3 Immunity to fast transients (burst immunity) IEC/EN 61000-4-4, level 3 Immunity to shock waves IEC/EN 61000-4-5 Radio frequency in common mode IEC/EN 61000-4-6, level 3 Voltage dips and breaks (AC) IEC/EN 61000-4-11 Immunity to damped oscillatory waves IEC/EN 61000-4-12 Conducted and radiated emissions Class B (*) in accordance with EN 55022, EN 55011 (CISPR22, CISPR11) group 1 (*) Except configuration (88 970 1.1 or 88 970 1.2) + (88 970 250 or 88 970 270) + 88 970 241 class A (class B in a metal enclosure) Operating Temperature -20 →+70 °C except CB and XB versions in VDC : -30 →+70 °C (+40 °C in a non-ventilated enclosure) in accordance with IEC/EN 60068-2-1 and IEC/EN 60068-22 Datasheet Product Datasheet User Manual
