Product Details

Polyphase STS Prepayment Meters Low Credit Warning Smart Power Meter

 

The CA368-G is a GSM / GPRS communication three phase four wire ( three wire available on request) smart electric meter compliant with STS prepayment encryption standard and DLMS/COSEM protocol (optional). It is designed to exchange data with a back-end server system (HES) for AMR / AMI smart metering applications such as automatic meter readout, on-demand and remote load control overriding consumers', element setting, etc.

 

The CA368-G  is produced by ISO9001 standards with IP54 rating protection, It has a build-in power supply  that allows it  to operate stably even in brownouts or voltage dips. A surge arrestor makes the meter sustaining 13kV lightening. 

 

 

 Main Features

1) Operatable in brownouts and voltage dips

2) Surge protection for lightening

3) Operates in prepayment and credit mode

4) Load Profile and maximum demand record (optional)

5) 3 elements 4 quadrant active and reactive energy measurement

6) Fraud detection

7) Prepared for AMR AMI facilities

8) IEC 62056-21 and DLMS/COSEM compliant

 

 User benefits

a) Quick and easy to install due to BS footprint mounting

b) Low operational and maintenance cost

c) Durable and reliable for unstable grid environments

d) Flexible payment settings for emergency unit, power limitations, etc.
