The CA368 smart meter can measure electricity from alternative power sources such as diesel generator power. It is designed for dual power source scenarios in those grid-unstable areas. . It is a BS footprint and three-phase four-wire meter that can bear 10 A to 100 A current. The voltage of each phase is 230V (60% 120% Un). Furthermore, the CA368 is designed as an STS keypad prepaid meter, operating the prepaid function based on the 20-digit STS Token. The meter will shut off the power automatically when the user consumes all credits in it.
Built-in RF communication modules for the CA368 will allow it to support the development of an AMR management system. The data concentrator collects data from nearby RF three-phase prepaid smart meters by RF communication and then uploads the data to our cloud server by GPRS. You can remotely read and monitor the meters and switch on/off the relay.
Main Features
• Compliant with STS (Standard Transfer Specification)
• Com port for IR optical & RS485
• Automatic disconnection when Credit is used up
• Flexible Power limit and low credit warning configuration.
• Tamper detection and event recording such as opening cover, reverse connection, black-out
• Dual power source working on both prepayment and credit mode
• Maximum demand measurement and load profiling (on request)
User Benefit
• BS footprint, easy to install
• Low operational and maintenance cost
• PLC/ RF/ GPRS/GSM communication for AMR/AM I features on your request
• Meter provides various valuable information by punching in Calin's shortcodes
