Single Phase Smart Energy Meter with Interchangeable Module

General introduction

Single Phase Smart Energy Meter with Interchangeable Module can measure the import and the export active energy,and is with TOU and step tariff functions, and can be with PLC or RF module for communication, and can be controlled to disconnect or reconnect the load remotely.

Main functions

1. Display and indication: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.

2. Metering and measurements: It can measure the import and the export active energy and the total active energy. The total active energy can be configured by the import and the export active energy as per the requirements. It can measure voltage, current, power, power factor, neutral current(optional), etc.

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. 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 time intervals and 254 holidays.

4. Data Snapshot: It supports freezing which includes daily freezing,hourly freezing, occasional freezing, immediate freezing.

5. Event logs: It can separately record latest 10 times events, such as reset of events, reset of meter, power outage, programming, time correction, meter cover open,disconnection/re-connection,etc.

6. Communication interface: Interfaces are independent with each other. one far infrared communication interface, one RS-485 communication interface and one PLC/RF (PLC and RF can be changeable.) communication module interface.

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.
