ACREL Three Phase IoT Energy Meter with RS485 and Wireless Communication
ACREL Three Phase IoT Energy Meter with RS485 and Wireless Communication is a three-phase wireless energy meter for monitoring electrical energy and key power parameters in low-voltage systems. It measures voltage, current, power, power factor, frequency and energy, with communication options including RS485, 470 MHz wireless, LoRa, 2G, NB-IoT, 4G and Wi-Fi depending on configuration. The compact meter is suitable for distribution boxes, energy monitoring systems and applications requiring remote collection of electrical data.
ADW300: Uses internal/wiring connections designed to select and work with compatible external secondary CTs based on site current.
ADW300W: Comes with pre-attached, non-detachable external current transformers.
The ACREL Three Phase IoT Energy Meter with RS485 and Wireless Communication provides three-phase electrical measurement for low-voltage distribution systems. It can measure active energy as well as voltage, current, active power, reactive power, apparent power, power factor and frequency.
Wireless communication allows the meter to be incorporated into remote energy monitoring and management systems. The manufacturer's information lists 470 MHz wireless communication as well as optional LoRa, 2G, NB-IoT, 4G and Wi-Fi configurations. RS485 communication with Modbus-RTU is also supported.
The meter supports several measurement and monitoring functions, including harmonic measurement from the 2nd to 31st harmonic, voltage and current unbalance measurement, and optional temperature and residual current monitoring. Four digital inputs and two digital outputs are available on the relevant configuration.
How it works
- The meter measures three-phase electrical parameters and energy consumption from the connected electrical system.
- Measured values can be viewed through the LCD and collected through RS485 or the selected wireless communication interface.
- RS485 communication uses Modbus-RTU for connection with compatible monitoring or management systems.
- Depending on configuration, data can be transmitted using 470 MHz wireless, LoRa, 2G, NB-IoT, 4G or Wi-Fi communication.
