Q：What's the biggest advantage of ADW300A?

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 address, baud rate, check bit was correct by using keypads on the meter.

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.
