AC220V 50Hz NB-IoT Electricity Meter with DL/T645-2007 Protocol Smart Energy Meter for Reliable Power Measurement

Introduction

This device is designed by advanced SOC single-chip processing system and manufactured by SMT process. It has the characteristics of simple circuit, high reliability and high measurement accuracy. It can realize active/reactive energy measurement, current, voltage, power and power factor measurement. Through NB-loT (narrowband Internet of Things) wireless communication, it has good anti-interference and anti-attack performance, wide operating temperature range, and can work stably and reliably for a long time.

It is suitable for users who implement single-rate electricity prices, such as small and medium-sized enterprises and institutions, commercial users, residential users, secondary circuit users, single-phase power equipment with narrow space, photovoltaic two-way measurement and charging pile measurement, and realize remote centralized reading. Product standard: GB/T17215.321.

Product features

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℃.
