Mini Grid 20 Digits Token Three Phase Energy Meters , Low Credit Warning Tamper Protection

The CA368 is designed for high-power solar Mini Grid or main line measurement. The CA368 is BS footprint and three phase four wires meter, which can bear 10 A to 100 A current, the voltage of each phase is 230V (60%~120% Un). Furthermore, the CA368 is designed as STS keypad prepaid meter, operating the prepaid function based on the 20 digits STS Token, the meter will shut off the power automatically when the user consume all credits in the meter.

Built in a RF communication module for the CA368, will lead to the CA368 can support to developing a AMR management system. The data concentrator collect the data from nearby RF three phase prepaid smart meters by RF communication, and then upload the data to our cloud server by GPRS. You can remotely reading and monitoring the meters, and also can switch on/off the relay remotely.
