ADW series din rail energy meter is mainly used for metering three phase active energy on low voltage network or medium voltage. There are RS485,4G,NB-IoT,WIFI communication way in order to help customers check, get and manage the value of energy consumption remotely.
It can be installed in distribution box flexibly, achieving the different demand of measurement and statistics of distribution on different areas and different loading. Besides, it can be equipped with other modules such as temperature measurement and residual current measurement.
It also could work with our IoT platform to help customers to check all parameters remotely.
Acrel ADW300 3-phase wireless smart energy meter moniter 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.

1. What's the biggest advantage of ADW300?
ADW300 has its built-in wireless communication module which allow it to realize 4G LTE, WiFi, NB-IoT, LoRa upstream communication without using extra IoT gateways. For the application scenarios when the meters can't be of centralized installation, ADW300 will usually be the best option for monitor 3-phase circuits that were far from each other.
First, check if the wiring of RS485 communication line was loosen or wired incorrectly.(like reversely wiring the A,B terminal).
Next,inspect if the meter's setting of address, baud rate, check bit was correct by using keypads on the meter.
3. What if LoRa communication of meters malfunctioned?
First, use USB to RS485 serial converter to connect the meter with computer. Then use adjustment software to check if setting of meter is on consensus with the setting of master station.(setting of channel and spreading factor--SF)
If setting remain the same, then it might be due to large interference of work site or the excessively far range between meter and host. In that case, it's recommended to use chuck antenna or set a new master station nearby.
