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

Acrel ADW300w 3-Phase Wireless Energy Monitor FAQs
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.
How should I deal with RS485 network communication malfunction?
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.
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.
What's the difference between ADW300 and ADW300W?
ADW300 has internal current transformers and can select compatible current transformer according to the site current to realized a secondary connection via CTs.
ADW300W on the other hand, has external current transformers.(non-detachable or it will damage the meter) This kind of design extremely ease the wiring and installation if the work-site already has
CTs.
What do 3×57.7/100V,3×220/380V,3×380/660V,3×100V,3×380V,3×660V represent respectively?
The meter’s spec of 3*100V,3*57.7/100V is suitable for high voltage power system while pairing with PT(potential transformer or voltage transformer). Beside, 3*100V represent 3-phase 3-wire and
3*57.7/100V represent 3-phase 4-wire.
The meter’s spec of 3*220/380V,3*380/660V,3*380V,3*660V is suitable for low voltage power system(directly connect with meter). Meanwhile,3*380V,3*660V represent 3-phase 3-wire and
3*220/380V,3*380/660V represent 3-phase 4-wire.
