Overview

Overview: DDZY315-4G/NB/WIFI wireless IoT smart meter adopts a dedicated high-performance MCU chip, embedded IoT communication module (NB/4G/WIFI/LORA), with optoelectronic isolation RS485 communication interface, infrared communication interface, LCD liquid crystal display, and built-in high-power magnetic holding relay. The performance indicators comply with the technical requirements of the national standard GB/T 17215.321-2021 and the power industry standard DL/T614-2007 for electric energy meters. Mainly used for the construction or renovation of student apartments, employee dormitories, commercial complexes, etc., without the need for wiring construction, it can be installed and connected to the internet immediately, realizing remote meter reading, prepayment of electricity bills, low quantity prompts, power outages due to arrears, and safety electricity management and report statistics printing, effectively solving the problem of charging and eliminating safety electricity hazards.

Product Details

Smart meter dedicated MCU and metering chip, with measurement accuracy higher than B (1.0) level.

● LCD large screen displays total power consumption, remaining power.

4G/NB-IOT/WIFI wireless IoT communication, compatible with optoelectronic isolation RS485 communication interface, lightning protection, surge protection, and anti-interference.

Automatic power outage for overdue payments, automatic incoming calls for recharging, and reminders for minimum balance.

● Safety management functions such as remote manual power on/off, timed automatic power on/off, overload tripping, time limited current, temperature detection, infrared remote control, etc.

Built in hardware clock circuit, with local data storage, supports remote precise timing and rate setting.

Measure and record electrical parameters such as voltage, current, power, and power factor.

● Record events such as zeroing, timing, remote tripping, and remote closing.

● Independently embedded software to ensure normal operation when disconnected from the internet, realizing metering deduction and policy control, strict password verification and security authentication,

Data transmission is secure and reliable.

Built in 4G/NB-IOT/WIFI IoT wireless module, does not require a gateway to directly connect to the background, and can customize dual control and dual metering functions.

The dual circuit smart meter can independently measure and strategically control the two circuits of dormitory air conditioning and lighting sockets.
