Description
This electric meter is designed to measure three phase four wire AC active energy, suitable for three phase electric equipment and small and medium-sized enterprises and institutions, commercial and residential users who are charged by multi-rate tariff. The meter meets IEC62053-21 and IEC62052-11 standards. Meter reading can be achieved by RS485 communication network.
Features
1. Active energy is measured bi-directionally and total, forward and reverse electricity can be showed.
2. Three phase realtime current, voltage, active power, reactive power, power factors and frequency measurement and display.
Interval electricity display available and it can be reset by pressing a button.
4. LCD shows reverse symbol if reverse electricity is measured.
5. LCD will show phase loss symbol if any phase loses.
6. Measurement for phase loss. The metering precision will not be influenced if any one phase or two phases of three phase four wire meter cut off.
7. Four kinds of rates (T1, T2, T3, T4) and 14 different time intervals could be set.
8. Bills could be automatically monthly charged. Electricity data of last 12 months could be saved. Data could be read through RS485 communication terminal
9. RS485 data communication terminal, compatible with DL/T645-2007 and MODBUS-RTU agreements.
10. Far infrared communication available.
11. Two wire energy pulse output for active and reactive energy passive pulse output.
12. While power cut, all storage data will not lose and can be saved for more than 15 years.
13. Able to sum up or reset accumulative working time and total electricity consumption during that time.
14. Meter width is only 70mm. 35mm DIN-rail installation. Similar shape as 4P breaker.
