Single-phase electronic energy meter (wall-mounted)

Single-phase electronic energy meter (wall-mounted)

Product Introduction

The electricity meter features NB-IoT narrowband IoT wireless communication, offering excellent anti-interference and attack

resistance. It operates reliably over a wide temperature range and maintains long-term stability. The design boasts a simple circuit, high

reliability, and precise measurement accuracy.

Designed in accordance with GB/T17215.321-2021, DL/T645-2007, and Q/GDW1828-2013 standards.

The electricity meter measures single-phase active power and is suitable for users who can realize wireless transmission and control integrated energy management.

Product Features

■The meter has the function of measuring forward, reverse and combined active power; the

combined active power can be selected from forward and reverse active power;

■Time-of-use metering: The meter supports four rates: peak, off-peak, flat, and valley. You can set two annual time zones and at least

14 time periods within 24 hours. The minimum interval of a time period is 15 minutes, and the time period can be set across midnight.

■Measurement function: The meter can measure voltage, current, active power and power factor of the power grid;

■Communication features: The electricity meter supports RS485 and IoT 4G communication.

■Valve control function: When the remote sends the command of trip and close, the built-in switch can

make the corresponding action to realize remote control, and can record the last 10 trip and close events.
