Energy consumption measurement IoT instrument 4G communication multifunctional instrument

1、 Product Overview

Energy consumption measurement IoT instrument 4G communication multifunctional instrumentMainly used for measuring three-phase active energy in low-voltage networks, it has the advantages of small size, high accuracy, and rich functions. It adds a current sampling mode for external transformers, making it convenient for users to install and use in different situations. It can be flexibly installed in the distribution box to meet the needs of sub item energy metering, operation and maintenance supervision, or power monitoring for different areas and loads.

2、 Energy consumption measurement IoT instrument 4G communication multifunctional instrument Main functions

1. Measurement function

The ability to measure all electrical parameters includes voltage U, current I, active power P, reactive power Q, apparent power S, power factor PF, phase angle between voltage and current Φ, voltage imbalance, current imbalance, frequency F, 31st harmonic, odd and even total harmonic content, and total harmonic content. Among them, voltage U is rounded to 1 decimal place, frequency F is rounded to 2 decimal places, current I is rounded to 3 decimal places, power P is rounded to 4 decimal places, phase angle Φ is rounded to 2 decimal places, and imbalance △ is rounded to 2 decimal places.

如： U = 220.1V，f = 49.98HZ, I = 1.999A, P = 0.2199KW, Φ= 60.00°, △=0.00%

Supports 4-channel temperature measurement and residual current detection.

2. Measurement function

It can measure the current combination of active energy, forward active energy, reverse active energy, inductive reactive energy, capacitive reactive energy, and apparent energy.

3. Time-sharing function

Two sets of time slot tables, one year can be divided into four time zones, each set of time slot tables can have 12 daily time slots and four rates (F1, F2, F3, F4 are peak and flat valleys). The basic idea of time of use billing is to treat electricity as a commodity, using economic leverage to increase electricity prices during peak periods and lower prices during off peak periods, in order to reduce peak hours, improve electricity quality, and enhance overall economic benefits.

4. Demand function

The relevant concepts regarding demand are as follows:

The default demand cycle is 15 minutes, and the slip time is 1 minute.

It can measure 8 types of three-phase currents, including A/B/C, forward active power, reverse active power, inductive reactive power, capacitive reactive power, apparent power, and occurrence time.

Display real-time 8 types of demand, namely A/B/C three-phase current, forward active power, reverse active power, inductive reactive power, capacitive reactive power, and apparent power demand.

5. Historical electricity statistics function

Can provide historical electricity statistics for December (including electricity from 4 quadrants and various rates)

6. Switching input/output function

There are 2 switch outputs and 4 switch inputs. The switch output is a relay output, which can achieve "remote control" and alarm output. The switch input can not only collect and display local switch information, but also achieve remote transmission function through the RS485 of the instrument, that is, the "remote signaling" function.

7. Wireless communication function

ADW300 supports 470MHz LORA communication, 2G, and NB communication.

8. Communication instructions

This instrument adopts MODBUS-RTU protocol or DL/T645 protocol. Please refer to the relevant protocol standards for the specific protocol format, which will not be elaborated here.
