Measuring Centres MC 320 - Energy Meter, MC 330 - Multimeter USE For electricity distribution and energy production companies, utilities, dwellings, energy management solution providers, industry, business buildings, designers of small power stations, panel builders, etc. Main features are: • Measurements of instantaneous values for more than 60 quantities (U, I, P, Q, S, PF, PA, f, j, THD, MD …) • 4 Energy counters • Accuracy class U, I, P 0.5 (Active energy Class 1) • Large frequency range from 16 2/3 Hz to 400 Hz • Up to 2 tariff inputs (option) • Up to 2 pulse or relay outputs (option)...

Measuring Centres Multimeter MC 330, Energy Meter MC 320 Accuracy Accuracy is presented as percentage from nominal value of the measurand except when it is stated as an absolute value. Measurand Rms phase voltage (U1, U2, U3, Uavg, MD) Phase-to-phase voltage (U12, U23, U31, Uavg) Phase and phase-to-phase angle (ϕ, ϕ12, ϕ23, ϕ31) Active, reactive and apparent power Active energy Reactive energy Pulse output Inputs Inputs signals Nominal frequency range Measuring frequency range Maximal value Power supply Universal Power supply Nominal frequency Safety Protection clas II 600 v rms,...

Measuring Centres MC 760/UMC 760 - NETWORK ANALYZER, MC 750/UMC 750 - NETWORK RECORDER USE The MC 760/UMC 760 network analyzer is used for permanent analysis of electric voltage quality in compliance with the EN 50160 standard. Records are stored in the internal memory for the period of the last 3 years. Moreover, more than 170,000 deviations of the measured quantities from the standard values are stored, which enables finding of eventual reasons for the problems on network. Optional limits and required quality in a monitored period can be defined for each monitored characteristic. The...

Measuring Centres MC 760/UMC 760 - NETWORK ANALYZER, MC 750/UMC 750 - NETWORK RECORDER Handling the costs A special meter function is cost evaluation of energy (active, reactive and total) by tariffs. The meter itself enables tracing the energy costs in optional currency. The meter calculates consumption in optional currency by means of the adjustable tariff clock and electric energy price. Input / output modules The modules are available with double inputs/outputs using a common connection contact (except a bistable alarm module - 1 output, 3 terminals). The meter is available without,...

Measuring Centres MC 740/UMC 740 - Multifunction meter USE The MC 740 multifunction meter is used for monitoring and measuring electrical quantities of a three-phase electric-energy distribution system. The meter is provided with 32 program adjustable alarms, up to four inputs or outputs and communication. The meter can be set and measurements can be checked with the RS 232/RS 485 or Ethernet communication. The meter also functions as an electricity meter, with the additional function of cost management by tariffs. A tariff input or a tariff clock can be set. At tariff clock setting, four...

Measuring Centres MC 764 - NETWORK ANALYZER, MC 754 - NETWORK RECORDER, MC 744 - MULTIFUNCTION METER DESCRIPTION The meter is intended for measuring, analysing and monitoring single-phase or three-phase electrical power network. The meter measures RMS 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, THD phase angles, etc.) from the measured signals. USE Meters from MC7x4 series are designed for environments where beside measurement of threephase...
