Acrel ADW300 wireless kwh meter is mainly used to measure three-phase active electric energy of the low-voltage networks. With RS485 communication and 470MHz wireless communication function, our ADW300 4G smart power meter is convenient for users to monitor, collect and manage electricity consumption.

Acrel ADW300 3 phase wireless energy monitor can be flexibly installed in the distribution box to realize the measurement, statistics and analysis of sub-item electric energy of different regions and different loads

Measurement: 3 Phase voltage, current, power, power factor, etc.
Communication: RS485, LoRa, 4G, WIFI, LoRaWan

Max demand measure
Accuracy: Class 1.0

Acrel ADW300 3-Phase Wireless Energy Meter Diagram
There are four modes of connection like 3-phase 4-wire (current connected via CT), 3-phase 3-wire (current connected via CT), 3-phase 4-wire (current connected via PT and CT) and 3-phase -wire (current connected via PT and CT). Two-way Digital output and four-way Digital input. Record the historical data on electricity consumption covering the previous 12 months. Acrel ADW300 series supports LORA, 2G, NB, and 4G communications

3-Phase Smart Meter Installation & Use
Step ①: Correctly install&wire meters
1. 35mm DIN-rail installation
2. 3-phase 4-wire or 3-phase 3-wire methods
3. Voltage signal input via direct connect or PTs
4. Current signal input via CTs or Rogowski Coils
5. Power supplied by 85~265Vac L-N power source

Step ②: Download&Register IoT APP
1. Download of IoT EMS APP
2. Register your account with 3-month Free Trial
3. Or contact us to get Test Account

Step ③: Add Meters to your Account
1. Acrel ADW300 smart energy Meters are recognized by a unique SN code
2. Scan QR code to add the wireless power consumption meter to your account
3. Edit CT&PT ratio according to paired CT&PT
4. If voltage input via direct connect, PT ratio set to 1 (Actual Power System Voltage = Voltage Signal Input of Meter)
5. If current input via 250A/5A CTs for example, CT ratio set to 50 (250÷5=50)
