1 GENERAL INFORMATION
1.1 DEVICE FEATURES
MMW03-M22CH is designed to measure:
„ Phase-neutral voltages;
„ Phase-phase voltages;
„ Phase current;
„ Neutral current;
„ Frequency;
„ CosØ;
„ Power factors;
„ Active powers;
„ Reactive powers;
„ Apperant powers;
„ THDV;
„ THDI;
„ 1-31 current and voltage harmonics.
Besides, MMW03-M22CH has numerous features such as:
„ Phase loss information and sequence error display;
„ Determining and saving in the memory of maximum and minimum values of current, voltage, frequency,
cosØ, power factor, THDV, THDI, active, reactive and apparent;
„ Measuring current, active power, reactive power and apparent power values and saving in the memory;
„ Setting alarm for current, voltage, frequency and power factor parameters;
„ 2 tariff meters. These meters record Import Active, Export Active, Import Reactive, Export Reactive;
„ Storing on hour counter (on hour), run hour counter (total energized time) and power interruption counter;
„ RS485 communication via MODBUS RTU protocol;
„ Digital inputs in order to start counter, 2nd tariff or run hour counter;
„ Digital outputs which can be set to energy meters or counters as output parameters;
„ 2 alarm relay outputs;
„ Avoiding unauthorized control by a 4-digit-password.
