In the current era of rapid development of smart grids and energy management, three-phase rail type IoT meters have become key equipment in the field of power monitoring due to their powerful functions and unique characteristicsADW300/4GCThe three-phase rail type IoT meter is a typical representative among them.

1、 Comprehensive and accurate measurement function

This electric meter can be regarded as a benchmark for power parameters“Measurement Master”It can accurately measure all electrical parameters, including voltage, current, active power, reactive power, apparent power, power factor, phase angle between voltage and current, voltage imbalance, current imbalance, frequency, etc., with high measurement accuracy, such as voltage retention1Decimal places, frequency retention2Decimals and other factors can provide extremely detailed and accurate data for power analysis. Meanwhile, it also supports4Road temperature measurement, with a wide temperature range and high accuracy±2℃The initial range for residual current detection is0～1000mAIt can also set the range multiple to ensure comprehensive monitoring of electrical safety.

2、 Powerful and practical measurement function

In terms of measurement, it performs excellently. Not only can it measure the current combination of active energy, but it can also measure forward active energy, reverse active energy, inductive reactive energy, capacitive reactive energy, and apparent energy separately, meeting the diverse needs of energy measurement in different scenarios and providing reliable basis for electricity billing, energy management, etc.

3、 Flexible and intelligent time-sharing and demand functions

The time-sharing function has high practicality, with two sets of time slot tables set up, allowing for one year of time-sharing4Time zones, each set of time period tables12Daily time period4By using economic leverage to achieve peak shaving and valley filling, improving electricity quality, and enhancing economic efficiency, a single rate (peak to valley) is implemented. The demand function is no less impressive, capable of measuring8Seed demand and display real-time demand, default demand cycle is15Minutes, slip time is1Minute, helping users accurately grasp the electricity load situation.

4、 Convenient and efficient historical data and switch function

It can be statistically analyzed12Historical electricity of the month, covering4Quadrant and various rates of electricity, convenient for users to trace and analyze long-term electricity consumption data. The switch input and output functions are equally powerful, with2Road switch output (relay output, can achieve)“remote control”And alarm output) and4Road switch input, not only can collect and display local switch information, but also throughRS485Realize remote transmission（“teleindication”Function).

5、 Advanced and diverse communication functions

This meter hasRS485Communication and470MHzWireless communication function, supportingLORATheNBand4GCommunication facilitates users to monitor, collect and manage electricity usage. It can be flexibly installed in the distribution box, easily achieving sub item energy measurement, statistics, and analysis for different areas and loads. It is widely used in online monitoring platforms such as power operation and maintenance, environmental supervision, etc.

The three-phase rail type IoT meter has become a powerful assistant for intelligent power monitoring due to its comprehensive and accurate measurement, powerful and practical metering, flexible and intelligent time-sharing and demand, convenient and efficient historical data and switch values, and advanced and diverse communication functions, promoting the development of energy management towards a more efficient and intelligent direction.
