Energy consumption monitoring of industrial production lines

In high energy consuming industries such as automobile manufacturing and steel smelting,ADW300/4GCan be deployed in various process distribution cabinets to monitor the power consumption of stamping machines, welding machines, and other equipment in real time. For example, a certain automobile factory discovered the existence of a group of air compressors by analyzing electricity meter data15%Redundant operation, with adjusted annual power savings of up to32ten thousandkWh.

Energy Efficiency Management of Commercial Buildings

Large shopping malls and office buildings use electricity meters to measure public lighting, air conditioning systems, and merchant electricity consumption separately, combined withAcrel-EIoTThe platform generates an energy consumption dashboard. After being applied in a commercial complex in Shanghai, the peak load in summer decreased by optimizing the air conditioning operation strategy18%Save over one million yuan on electricity bills annually.

Charging piles and distributed energy access

In electric vehicle charging stations, the electricity meter can measure the amount of charged electricity and upload it to the operation platform, supporting billing based on power, time, or electricity. At the same time, its bidirectional metering function is adaptedV2GScenario of (vehicle to grid), achieving interactive regulation between electric vehicle batteries and the grid.

Pre paid management of residential communities

Through rail installation and4GRemote communication, electricity meters can be integrated into the property management system, supporting mobile phonesAPPRecharge, balance reminder, remote closing and opening functions. After deployment in a residential area in Hangzhou, the dispute rate of overdue fees has decreased90%Improving the efficiency of property fees3Twice.

3、 Technical advantage: the balance between small size and large functionality

ADW300/4Gadopt standardsDIN35Guide rail design, with a volume of only126×89×74mmIt can be integrated and installed with other electrical components such as circuit breakers and contactors.
