China Supplier DT(S)S Three Phase Four Wire Din Rail Electric Meter^ Register Active Digital Din Rail Energy Meter With Alarm

1.Starting
When the rated voltage, rated frequency and power factor is 1.0, the loaded current is 0.004Ib(class1)、0.005Ib(class2), the meter shall starts and measures energy continuously.

2.Creeping
When the voltage circuit is loaded with a voltage 1.15 times of the rated voltage and there is no current in the current circuit, the meter is supposed not to output more than one pulse.

3.Working Voltage Range
Normal Working Voltage:0.9Un～1.1Un
Working Voltage Limit:0.0Un～1.15Un

4.Power Loss
Power loss of the voltage line in each phase≤2W/10VA Power loss of the current line in each phase≤4.0VA 

5.Environment condition
Standard working temperature：-10℃～+45℃, 

Working temperature limit：-25℃～+55℃
Storage and transport temperature limit：-25℃～+70℃ 

Relative humidity: annual average≤75% 

Basic Error（balanced load basic error limit）

The Main Functions
1.Energy Measurement
It measures total active energy.With three phase power supply, the meter will keep measuring energy accurately even with one or two phases cut off.

2.Phase missing indication function
Three light indicators are used to indicate whether there is phase missing. Indicators A, B, and C indicate the missing of Phase A, Phase B and Phase C correspondingly.
