Product Description

Product Description

ADW300 Wireless 3 Phase WiFi Mqtt Power Meter with Cts for IoT platform

 Acrel Co.,Ltd. has experience of over decades in various kind of energy meters.Among them,ADW din rail electric energy meter is with mini

size,high accuracy,and it is easy to install. The ADW series have also got CE.

ADW300 wireless meter is mainly used to measure three-phase active power in low-voltage network.

It has the functions of RS485 communication,2G,4G,NB-IoT and 868MHZ/923MHZ/433MHZ Lora/Lorawan wireless communication.

It is convenient for users to monitor, collect and manage electricity.

It can be flexibly installed in the distribution box to realize the measurement, statistics and analysis of individual electric energy in different regions

and loads.

FAQ

Q:What's the biggest advantage of ADW300?

A: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.
 
Q:How should I deal with RS485 network communication malfunction?
A: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 addressbaud ratecheck bit was correct by using keypads on the meter.
 
Q:What if LoRa communication of meters malfunctioned?
A: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.
 
Q:What's the difference between ADW300 and ADW300W
A: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.
 
Q:What do 3×57.7/100V,3×220/380V,3×380/660V,3×100V,3×380V,3×660V represent respectively?
A: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.
