Main electrical performance indicators

1. Starting current

Connected through current transformer: active powerThe 1.0 level table is 0.002Ib.Direct access: activeThe 1.0 level table is 0.004Ib.

2. Diving

When the voltage circuit isMeasurement of electric energy meter with 115% rated voltage and no current in the current circuitThe trial output should not produce more thanOne pulse.

3. Power consumption

Voltage circuit power consumption≤1.5W/5VA，Normal operating voltage:0.9~1.1 rated voltageMaximum operating voltage:0.7~1.2 rated voltage

4. Operating voltage range

Normal operating voltage:0.9~1.1 rated voltageMaximum operating voltage:0.7~1.2 rated voltage

5. Environmental conditions

The standard operating temperature is-25℃～+55℃The maximum operating temperature is-40℃～+70℃Annual average relative humidity:≤75%

6. Instrument safety performance
The instrument indicators meet the requirementsGB/T17215.321-2008 "Level 1 and Level 2 Static AC Active PowerEnergy table "andGB/T17215.323-2008 "Level 2 and Level 3 Static AC Reactive Energy Meters"The prescribed requirements.

major function

1. Energy metering function

1.1 Energy metering function: metering active positive and negative energy, and separately metering negative energy.

1.2 Three phase power supply, one or two phases of power outage, measurement accuracy is not affected. three-phaseAfter power failure, all stored data will not be lost and can be maintainedMore than 10 years.

1.3 It has the function of coupling isolated active and passive pulse test port output (meeting the requirements of remote pulse output)Requirement, pulse width is80ms ± 20ms).

2. Alarm function:The alarm indicator light goes off when there is a phase loss.

3. Communication function

3.1 Communication can be achieved through handheld terminals or PCs to complete programming settings and meter reading. throughThe communication symbol lights up during communication, making it convenient, intuitive, and reliable.

3.2 Communication protocol Modbus RTU or 645 protocol is optional, specific identification codes can be found in the instruction manual.

4.Display function

4.1 Display various information using a wide temperature and large LCD display mode; The number of digits displayed for electric energy is 6, which is an integerNumber,2 is a decimal.

4.2 Equipped with automatic parameter rotation function, with a rotation time of 5 seconds.
