OEM Three Phase LoRaWAN Energy Meter EU868mMHz MID Approved for IOT Solution

1.Products Description

EM514012 is a three-phase four-wire electronic multi-functional rail meter.

The electricity meter offers options for post-payment and pre-payment modes, supports local communication via RS485 and remote communication via LoRaWAN, and uses the Modbus protocol.

It is equipped with a built-in holding relay. The local relay status can be set through RS485 communication, and the relay can be remotely controlled on/off via LoRaWAN communication, while also enabling remote meter reading. It is widely applicable to both household and commercial power distribution systems.

2.Features

(1) Measurement of bi-directional (forward&reverse) energy, active power, voltage, current, frequency, power factor, and demand quantity etc.

(2) Three Phase LoRaWAN Energy Meter:LoRa Communication LoRaWAN Protocol；Regional Frequency Band: EU868.

(3) Bidirectional Metering:Measurable forward and reverse active and reactive power and energy quantities

(4) Prepaid & Postpaid Model:Supports pre-payment of electric quantity and pre-payment of the electric amount.

(5) Built-in holding Relay: Remote control of electricity meter's on/off state

(6) Overcurrent Cut-off:Set the overcurrent threshold and the overcurrent cut-off recovery time. If the actual current exceeds the threshold, the relay will automatically cut off. After the set recovery time has elapsed, the relay will automatically attempt to close again.

(7) Alarm function:Overcurrent, overvoltage, frequency deviation, low balance/charge level, side cover/top cover detection.

(8) Event Log:Support event recording for recharge, overcurrent, overvoltage, frequency deviation, power outage, low balance/energy level, side cover/top cover detection, etc.It can record and store 20 pieces of data.

5. Why you need a 3 phase Lorawan energy meter?

Comprehensive Energy Monitoring: Three-phase systems are common in industrial, commercial, and large residential buildings due to their efficiency in delivering higher power. A 3-phase meter can accurately monitor the energy consumption across all three phases, providing a complete picture of total energy usage.

Wireless Long-Range Communication: LoRaWAN enables the meter to transmit data wirelessly over significant distances (several kilometers in open areas) with minimal power consumption. This eliminates the need for extensive wiring and allows for remote monitoring in hard-to-reach locations.

Reduced Infrastructure Costs: The long-range capability of LoRaWAN reduces the need for numerous gateways or repeaters, lowering the overall infrastructure costs for deploying a smart metering system.

Low Power Consumption: LoRaWAN technology is designed for low power consumption, allowing the energy meter to operate for extended periods on batteries, reducing maintenance and the need for a constant power supply.

Real-Time Data and Analytics: The meter can transmit energy consumption data at regular intervals to a central server or cloud platform. This enables real-time monitoring, data analysis, identification of energy inefficiencies, and potential cost savings.

Improved Energy Efficiency: By providing detailed and timely energy consumption data, businesses and building managers can gain insights into their energy usage patterns, identify areas for improvement, and implement energy-saving measures.

Cost Transparency and Billing Accuracy: Accurate monitoring of energy consumption ensures fair and transparent billing for tenants or different departments within a facility.

Remote Management and Control: Some 3-phase LoRaWAN energy meters may also offer remote control functionalities, such as load switching or tariff adjustments.

Easy Deployment and Integration: LoRaWAN networks are relatively easy to deploy, and the meters can often be integrated with existing building management systems or IoT platforms.
