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.

Zhejiang Risesun Science and Technology Co., Ltd.is a famous professional supplier of energy measuring meters and acquisition systems of consumed energy information, and it is a national level high and new technology enterprise with the business range of research and development, production, sale and after-sales service for energy measuring meters and acquisition systems of consumed energy information. Its main products cover smart energy meter, din rail energy meter, STS keypad prepaid energy meter, multifunction energy meter, acquisition terminal of special transformer, data acquisition system, charging pile of electric auto, metering box and etc. It is one of the companies with the most technical influence and development potential in the electric energy metering instrument industry of China.

Risesun is one of the earliest enterprises in meter industry forming  Management System of ISO9001:2008, ISO14001: 2004 and OHSAS18001: 2007. Moreover, a variety of leading products have passed quality certifications of the international authoritative organizations like the Holland KEMA, the European Union CE-MID, South Africa STS, Switzerland DLMS and etc.

Risesun has formally carried out the globalization management strategy. Its sales turnover has increased steadily year by year, with sales reaching 3 billion yuan in the past three years. Its products and solutions have already been successfully applied in a number of countries and regions, and have obtained the unanimous praises from customers. A main source of its sales revenues in the future will be from the international trade business.

Today's Risesun, just as a round of Oriental Sun, is rising and creating greater glories with the help of the national macroscopic policy good solution and its research and development potential.
