Acrel ADW200 DIN-Rail multi channel power meter with LoRa wireless

Typical application 

Multi-loop power meter, which can measure the grid parameters of 4 three-phase or 12 single-phase loops, including voltage, current, power, frequency, energy, demand, extreme value,total harmonic distortion rate,2-31 harmonic parameters such as wave,voltage and current imbalance,and multi-rate energy metering. The function module can be externally extended.

Common errors check and solve

1 The meter do not light after powered, or one path of voltage indicator do not light.

Suggestion: Please turn the screw to ensure that the meter needle has been punctured and contacted with the cable inner
conductor cable.

2 Meter’s wireless communication failure

Suggestion: Please connect RS485 interface on the meter and USB convert to 485 serial port to read the parameters, and
confirm whether the parameters are the same as the upper terminal wireless configuration (channel and spread spectrum
factor). If different, please modify the meter’s wireless parameters and retest the master terminal after the same, and if
the same, it may be the meter and master terminal are in a relative long distance. It is too far to communicate or the scene
is seriously disturbed. We can try to use the external antenna at the same time, or consider the newly added wireless
master terminals, and then test it.
