Brief Product introduction
Electronic energy meter (DDS5558 electric meters) is a new type single phase whole electronic meter.
It adopts micro-electronics techniques to measure electric energy , imported special LSI and newest SCM and periphery CMOS chip technique to design and make which can directly and accurately measure meter active energy consumption in positive direction. Its Data collection, disposal and save is finished by advanced SCM processor and electric and adopt 7 digits wide temperature type LCD with SMT techniques to display energy consumption data.
The meter completely accord with relevant technical requirements of Class 1 Single phase energy meter stipulated in international standard IEC62053-21 OR IEC61036.
Function and features
1.Favorable anti-electromagnetism disturbance,
2.Low power less
3.High accuracy
4.High overload,
5.Anti-sealing electricity
6.Reliable performance and long life.
Performance and principle
1 Circuit design and components choice of energy meter is according as wide range surroundings conditions so as to guarantee meter working stably for long terms.
2 Principle: Energy meter get voltage sampling signal from voltage transformer and get current sampling signal from current transformer, and get product signal of current and voltage from multiplication device, and bring energy measuring impulse by frequency transform which is direct ratio between frequency and product of voltage and current, the created energy impulse signal is sent to CPU by photo electricity coupling device.
Main technical data
Accuracy | Rated voltate(V) | Rated current(A) | Frequency(HZ) |
Class 1 | 220/230v, | 5/20,10/40,10/60 | 50HZ OR 60HZ |
Transport and storage
1 Transport and storage of the meter must not be shaken and must accord with stipulated IEC61036 or IEC62053-21.
2 The meter must be stored in the original packing box and the environmental temperature is in -25°C~+70°C, relative humidity shall exceed 95%, and there is not any corrosive gas. The ambient temperature shall not vary violently.
3 The meters should be in the original packing box and the boxes should be piled up no more than five cartons on the rack. The separate meters should be piled up no more than five pieces. The unpacked meter is not suitable for storage.
Maintenance and service
Within 18 months from the date of manufacture the use complies with all of above rules, if the meter still being sealed does not confirm to any technical requirements of IEC61036 or IEC62053-21, or of any certification of power department of measuring department, the manufacture guarantees to repair freely or to change.
