1. LCD digital display: total power, standard 6-digit integer + 2-digit decimal (999999.99kWh/kvarh).
2. Accurately measure the forward and reverse active power, and can display the total power, forward power, reverse power, and total reactive power.
3. Meter reading can be performed through the RS485 communication interface, DL/T645-2007 is in even parity mode, and MODBUS-RTU is in no parity mode.
4. The NB-loT communication protocol can be opened to connect to third-party systems. All wiring uses bottom inlet and outlet lines, and the external amplified antenna has a stable signal.
5. Remote control of the switch, after power failure, all stored data will not be lost and can be maintained for more than 15 years.
6. Working temperature: -20℃~+55℃.
7. Extreme temperature: -25℃~+70℃.
