STS Encryption Infrared Optical Prepaid single-phase Prepayment Meter

Photovoltaic (PV) power generation is growing fastly in South Asia and Africa, As mini-grid to effectively provide electricity for the remote area which the utility grid cannot cover. The CA168 is specially designed for PV solar generation mini-grid to measurement the power consumption, it can support 5A, 16A, 40A, 60 A current, 230V Nominal voltage, Class 1 accuracy class make sure the good measurement. We have built-in an RF module in the meter so that the monitoring and management system can be developed, the meter sends the data to the data concentrator by RF, and then the data concentrator uploads the data by GPRS. The repeater can extend the communication range for the data concentrator.
