LCD Display Din Rail KWH Meter , 3 phase power meter kwh Active Energy Measurement

Features:

• Three-phase power supply can assure accurate metering in case of cut off in one line(each line of the three-phase & three line) or two lines (any two line of the three-phase & four line;
• Indicative function for phase loss or voltage indication
• The signal will display after it test
• Each user (meter) responds to a card, well protect form forgery
• Once the remaining electric power quality is approaching the alarming power quality, the digital tube should be lighted to remind user of timely purchasing
• Once the electric consumption available is out, it should be auto cut-off
• Auto cut-off overload
• Date-copying function make the electricity department easier to manage
• Load switch
• The IC card pov/er selling control system has the function as power selling and using control
• Expansible Rs485.

Three phase four wire electronic DIN rail active energy meter is a kind of new style three phase four wire active energy meter, it adopt micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. The meter completely accord with relevant technical requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-21. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net. This meter has seven digits LCD displays shows the active energy consumption.

• And there are far infrared and RS485 communication module in it.
• Contact with all kind of AMR system conveniently It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation

Starting:

• When current transformer access: The starting current is 0.5%Ib
• When direct access: The starting current is 0.004Ib

Running with no-load:

• As no current in the circuit and the voltage value is 115% percent of the rated voltage, the testing output no more than one impulse.
• Insulation performance:
• All circuit interval of the meter can withstand impulse voltage with waveform 1.2/50µs, leak value 6kV, and it would not occur electric arc or rout as it is being tested at the same pole.

Operating voltage range:

• Normal working voltage: 0.9 - 1.1
• Rated voltage limit working voltage: 0.8 to 1.2 rated voltage

Power consumption:

• Voltage circuit power consumption ≤ 1.5W/5VA
• Current loop power ≤ 2VA

Environmental conditions

• Standard operating temperature: -20℃ - +75℃
• Annual average relative humidity
