Three Phase Smart Meter with Communication as per DL/T645-2007

General introduction
Three Phase Smart Meter with Communication as per DL/T645-2007 can measure import and export active energy,inductive and capacitive reactive energy, with TOU and step tariff functions, and can be optional with PLC or RF module. It can be controlled to disconnect and reconnect the load remotely.

Main Function
<sub>1. 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.
2. Measurement: It can measure voltage, current, active power, reactive power, apparent power, power factor, 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 for kWh are available.
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 to achieve the mutual switching. It can be set 14 time intervals and 254 holidays.
4. Data snapshot: It supports freezing which include daily freezing, hourly freezing, occasional freezing, immediate freezing.
5. Event logs: It can separately record latest 10 times events, such as power outage, programming, time correction, meter cover open and terminal cover open, disconnection and re-connection, reset of events, reset of meter, etc.
6. Communication interface: The meter has one infrared interface, one RS485 and one PLC or GPRS module interface. Interfaces are independent. The protocol of meter conforms to DL/T645-2007.</sub>
