Frequently Asked Questions
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. It is the best option for monitoring 3-phase circuits that are far from each other.
How should I deal with RS485 network communication malfunction?
First, check if the wiring of RS485 communication line is loose or wired incorrectly (like reverse wiring of A, B terminals). Next, inspect if the meter's setting of address, baud rate, and check bit are correct using the keypads.
What if LoRa communication of meters malfunctioned?
Connect the meter to a computer via USB to RS485 converter. Check if the channel and spreading factor (SF) settings match the master station. If settings are correct, use a chuck antenna or relocate the master station closer to reduce interference.
What's the difference between ADW300 and ADW300W?
ADW300 has internal current transformers for secondary connection via CTs. ADW300W uses external current transformers, which simplifies wiring and installation if the site already has existing CTs.
What do the various voltage specs (e.g., 3x220/380V) represent?
Specs like 3*100V are for high voltage systems pairing with PTs. Specs like 3*220/380V are for low voltage systems with direct connection. They also distinguish between 3-phase 3-wire and 3-phase 4-wire configurations.
