Overview ADW310 wireless energy meter is mainly used to
measure the active energy of low-voltage network. It has the
advantages of small size, high precision, rich functions, etc., and
has many optional communication methods. It can support RS485
communication, Lora, 4G and other wireless communication methods.
The current sampling mode of the transformer is convenient for
users to install and use in different occasions. It can be flexibly
installed in the distribution box to meet the needs of power
metering, operation and maintenance supervision or power monitoring
for different areas and different loads. ADW310 Main Function | Function | Description | | Display | LCD (field type) | | Energy Metering | Active energy metering (forward, reverse) | | Electricity Measurement | Voltage,current,power factor, frequency,active power,reactive
