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.
