DDSY , electrical prepaid meter;
Product Introduction
DDSY the single-phase electronic formula IC card
electrical energy table uses the large scale integrated circuit,
has the periphery part
few, structure simple, the reliability is high, the power loss low
status characteristic, may use in measuring the rating is the *0Hz
single phase AC the electrical energy.
This product may install in the room or outdoor
electric instrument box, adapts in the ambient temperature is **0
℃***-**5 ℃, therelative humidity is not bigger than under *5%
condition to use.
This product each performance index conforms to
GB/T***3 and in IEC******6 standard to single-phase electronic
formula electrical energy table complete specification. Function
and Features.
Used to measure active energy, can normally work over long time
without adjustment;
Prepaid by IC card;
Indicative function for phase loss or voltage indication;
One meter one card, with good anti-counterfeit feature;
Low energy alarm;auto power shut-off with no energy;
Large-capacity magnet latching relay, low consumption and high
reliability;
Present wattage, surplus wattage, accumulated wattage, load setting
value, alarm wattage, maximum load and current load display;
Deata write-back function, to write back accumulated wattage,
surplus wattage, overload frequency, abnormal power using time and
energy pulse constant to the electric power distribution system.
