Three Phase Four Wire AMI Energy Meter Electric Card Meters For Landlords

Three Phase Four Wire Multifunction Electronic Energy Meter

General Introduction

Three Phase Four Wire Mulifunction Electronic Energy Meter can measure the import and the export active energy, the inductive and the capacitive reactive energy, and is with TOU function. It has the anti-tamper function, it will alarm in time of detected tamper events, such as current reversal, voltage phase sequence reverse, meter cover open and terminal cover open, bypass, etc.

Technical specifications

Main functions

1. Metering and measurements: It can measure voltage, current, active power, reactive power, apparent power, power factor, etc. It can measure the import and export active maximum demand, and four quadrant reactive maximum demand. It is with high accuracy. Class 0.2S, Class 0.5S or Class 1.0 for kWh are available.

2. Display and indication: It adopts a large screen LCD with abundant graphics and hint text. The displayed contents can be scrolled automatically or by button, and the displayed items can be configured as per the requirements. It is with backlight. Meter can be read during power outage.

3. TOU: 4 tariffs; Built-in 2 sets of time zone tables and 2 sets of daily period tables, which can be configured as per the requirements. Moreover, the switching time for both 2 sets of time zone tables and 2 sets of daily period tables can be set and achieve the mutual switching. It can set 14 day period tables and 14 week tables and 100 public holidays.

4. Load profile: It can record the data of multi-channel load profile.

5. Anti-Tamper: The meter will alarm in time of detected the tamper events, such as current reversal, voltage phase sequence reverse, meter cover open and terminal cover open, bypass, etc.

6. Event logs: It can separately record latest 10 times events, such as power outage, programming, time correction, meter cover open, disconnection and reconnection, reset of events, reset of meter, etc.

7. Communication interface: The meter has one optical port, one RS485 and one RS232. These three interfaces are independent with each other.

Honorary Qualification

Risesun is with the fluent product manufacturing process, the reasonable artwork layout and the scientific production organization, and is one of the earliest enterprises in meter industry forming Three-in-one 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 devotes to creating its own brand, and has won many honorary titles, including China Famous Trademark, National High-tech Enterprise, Provincial Enterprise Technology Center of Zhejiang Province, Zhejiang Province Famous Company, Zhejiang Famous Brand Products, AAA Level Enterprise to Keep Contract and Credit, AAA Class Tax Paying Enterprise, and successive Top 100 Good Credit and AAA Enterprise of banking system. With its brand and other comprehensive advantages, Risesun has been elected as the director unit of China Instrument and Meter Industry Association, and the member unit of the national standard revision group of National Standards Technical Committee for Electrical Measuring Instruments.

Risesun sets up a R&D center both at Wenzhou headquarters and Shenzhen branch with a manufacturing base in Wenzhou. After many years of hard work, Risesun has acquired many advanced technologies in such fields as energy measuring meter and acquisition system of consumed energy information, such as wide-range and high-precision measuring technique, intelligent-control technology, anti electromagnetic interference technology, self-adaptive communication technology and alike.

Several RD projects of Risesun have got the grants and awards from the provincial and municipal governments in Zhejiang Province.

Each of honors accompanies each step of the growth of Risesun, but Risesun's people have always believed that honor only belongs to yesterday, and does not represent today and tomorrow, and all that we have now is to give us a reason to climb higher. For better tomorrow, Risesun's people work hard as always.

AMI Meter System advantages

1.Diversity of management:
Managing range covers the different types of energy consumed objects, such as Substations, Users with special transformer, Distribution transformers, Residential Users, etc. It can configure the relevant managing function according to the type of object.

2.Flexibility of configuration:
2.1 Function modularization: It can customize the equipment and separately deploy the modules according to the size of the management scale.
2.2 The function is hierarchically designed, which can guarantee clear logic, convenient maintenance and the stable operation.

3.Compatibility of equipments:
The users can choose the appropriate mode of network (such as GPRS, PLC, WSN or 485), the collection equipments (such as various energy meters or concentrators) and the operation protocol of equipments according to their own situation. The system can provide support or expansion.
