ACREL Single-Phase Wireless Energy Monitoring Meter
ACREL Single-Phase Wireless Energy Monitoring Meter is a single-phase wireless energy meter for monitoring electrical energy and electrical parameters in low-voltage networks. It measures voltage, current, power, power factor, frequency and energy, with optional RS485, 470 MHz wireless, 4G, Wi-Fi, temperature and digital I/O functions. Its external current transformer design allows flexible installation in distribution boxes and monitoring systems.
D10: Designed for lower current ranges, rated at 5(20)A via an external CT.
D16: Designed for higher current loads, rated at 20(100)A via an external CT.
The ACREL Single-Phase Wireless Energy Monitoring Meter is designed for electrical energy measurement in low-voltage networks. It provides measurement of single-phase electrical parameters and active and reactive energy, including forward and reverse energy measurement.
The meter uses an external current transformer for current measurement, allowing the current sensing arrangement to be separated from the main meter body. Acrel specifies a rated current of 20(100) A AC for the ADW310 configuration documented on its product information.
Communication options vary according to the selected model. RS485 with Modbus-RTU is available, while wireless versions can provide 470 MHz, 4G or Wi-Fi communication. Wi-Fi versions support MQTT and Modbus-TCP according to Acrel's published specifications.
How it works
- The meter measures the single-phase electrical supply and obtains current through an external current transformer.
- It calculates electrical parameters including voltage, current, active power, reactive power, apparent power, power factor and frequency.
- It records active and reactive energy, including forward and reverse energy measurement.
- Depending on the selected configuration, measurement data can be communicated through RS485, 470 MHz wireless, 4G or Wi-Fi.
- Optional functions can provide temperature measurement, digital input and digital output.
