Product Description

Three Phase Prepaid Electricity Meters , Plc Rf Commercial Electric Meter

A CA368 and a customer interface unit (CIU) together makes the CA368-S,  a four-wire, 100 Amp per phase,split type  keypad based prepayment meter. The meter is finished in a compact BS footprint enclosure. It is ideal for residential homes, commercial and light industrial applications. 

The CIU is installed within customer's premise and the main meter is usually locked away from consumers' premise in a kiosk, cabinet or meter box on the pavement or mounted on the pole. The main meter communicates with the CIU via Power Line Carrier, Radio Freqency, or LoRa, a low power consumption wireless technology. This non-wired split feature makes the meter immune to most tampers and facilitates quick and easy inspection by utility or service providers with no need to visit consumers.

The CA368-S also communicates with a back-end central server through wireless communication forAMR AMI  functionalities. It is an ideal all-in-one revenue protection device for utility and service providers.
