Product Introduction
This energy meter employs an advanced SOC microcontroller system design and SMT manufacturing
process, featuring a simple circuit, high reliability, and high measurement accuracy. It supports active/
reactive power measurement, current, voltage, power, and power factor measurement, and is equipped with
NB-IoT narrowband IoT wireless communication. With excellent anti-interference and attack resistance, it
operates across a wide temperature range and ensures long-term stable and reliable performance.
The electricity meter measures the active power of single-phase two-wire, which is suitable for secondary circuit users with single-rate
electricity price, or for the internal space of single-phase electrical equipment, and for two-way photovoltaic measurement, charging
pile measurement and remote data collection.
Product Features
■The total energy is displayed digitally on the LCD screen, with a standard configuration of 6-digit integer and 2-digit decimal (999999.99 kWh/kVAh).
■Accurately measure forward and reverse active power, and display total power, forward power, reverse power, and total reactive power.
■ NB-LTE Narrowband IoT delivers high communication stability and low power consumption, compatible with China Telecom’s AEP platform and Mobile Oneweb.
■The button allows setting the Modbus communication address and baud rate.
■Real-time current, voltage, active power, reactive power, power factor, and frequency measurements are displayed.
■Remote closing and opening control
■The meter reading operation can be performed through the RS485 communication interface, with a baud rate ranging from 1200bps to 9600bps.
■ The NB-oT communication protocol supports open integration with third-party systems
■External expansion enhances the antenna, ensuring stable signal
■Passive pulse output, pulse indicator light indicates working status
Note: The pulse terminal requires no wiring and is used only for error calibration tests.
■After power failure, all stored data will not be lost and can be kept for more than 15 years
■The meter is 76mm wide, mounted on a 35mm standard rail, and has a 4-pole switch-like appearance.
■All wiring uses bottom entry and exit
