Description
The two types of electricity meters are used to measure single phase two wire AC active energy. Utilizing SMT (Surface mounting technology) to manufacture, the meters completely accord with the international standard IEC62053-21.RS-485 data communication terminal is available upon request to perform remote data collection.

Features
1. Active energy is measured bi-directionally and reverse electricity will be measured and counted into total electricity.
2. Reverse indicator light
3. Impulse indicator light will flicker to show working status when passive pulse outputs.
4. Remote meter reading is available through RS485 communication interface conform to MODBUS-RTU and DL/T645-2007.
5. Support far infrared communication
6. Continuous data saving after power failure and lasting for more than 15 years.

Optional Function
1. Electricity display and battery power while black out (can be customized)
2. Built-in relay and remote switch (can be customized)
3. M-BUS meter reading system
4. Bi-directional electricity display, independent forward and reverse electricity display, suitable for the photovoltaic industry.
