Single Phase Energy Meter DDS28-1 Electric Power Meter Electric Meter

1.Stable measuring accuracy, general speaking, it would be free from effect of frequency, temperature, voltage or high order harmonic. After leaving the factory, it is unnecessary to make further regulation to the complete machine, it is allowable to prolong the verification period, which sharply reduces the testing and inspection work of power department, it has obviously advantage in reliability when comparing with other similar products. 

2.Bi-directional measuring function, it is able to measure out the forward and reverse active energy accurately, and the reverse active energy would also be reckoned in forward value.    energy meter electrical

3. It is able to reserve the data of electric quantity permanently without help of standby battery.

4. The register will be driven by single chip directly, preventing pulse-loss phenomenon during power on or off, which guarantees consistency of meter reading data and register indicating value, avoids unnecessary dissension due to inconsistency of data.    remote control energy meter

5. Adoption of optical coupling isolated passive pulse output interface .

6.This meter is featured with wide load, high accuracy, high reliability, high sensitivity, straight error curve, low power consumption, small volume, light weight, energy saving, material saving, direct register display, etc.

1.Starting: under conditions of reference voltage,reference frequency and power factor is 1.0, the meter should be able to start and measure the electric energy normally when meter of class 1 is 0.4%Ib and meter of class 2 is 0.5%Ib.

2.current in current circuit, testing output of the meter shall not produce more than one pulse. 

3. Power consumption: ≤2W (5VA).

4.Ambient conditions Standard working temperature: -25℃～55℃

    Limiting working temperature: -25℃～60℃ 

    Note: limiting working temperature for special requirements: -40℃～70℃

5.Outline and installation dimension drawing
