Single Phase Multifunction Electronic Energy Meter
General introduction
Single Phase Multifunction Electronic Energy Meter is used not only for measuring the single phase a.c. active energy, but also for measuring the Maximum Demand, and it can be with Infrared port or RS485 for communication, and it is also with the function of multi-tariff and the anti-tamper, etc.. It adopts the high quality long lifetime components and SMT manufacturing craft, and is reliable in performance. It conforms to the standards of IEC 62053-21:2003, IEC62052-11:2003 and IEC62056.

Q&A
Q: What kind of timing functions do smart energy meter have? How about the accuracy?
A: Smart energy meter adopts built-in hardware clock circuit with temperature companion function, which has automation conversion function among calendar, time and leap year; the output frequency of internal clock terminals of energy meter is 1 Hz. Within the temperature range of 25～+60℃, the clock accuracy is ≤±1s/d; Under the reference temperature (23℃), the clock accuracy is ≤±0.5s/d. It adopts green environmental protection lithium battery as standby power supply, and the capacity of battery is more than 1.2Ah. During the life cycle of energy meter, the battery needn’t to be changed, and it can make internal clock work correctly for more than 5 years after power outage.
