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 flat 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. Interval electricity display available and it can be reset by pressing a button.
3. Reverse electricity will be measured. Reverse indicator light available.
4. Three phase realtime current, voltage, active power, reactive power, power factors and frequency measurement and display.
5. Passive pulse output, impulse indicator light will flicker while the meter is working.
6. Phase loss LED light indicator
7. 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.
8. RS485 data communication terminal, compatible with DL/T645-2007 and MODBUS-RTU agreements.
9. While power cut, all storage data will not lose and can be saved for more than 15 years.
10. Meter width is only 125mm. 35mm DIN-rail installation. Similar shape as 7P breaker.
Optional Function
Electric quantity will display and battery power while black out.
