Card Type Prepaid Wireless Electricity Meter Residential 3 Phase Kwh Meter
The CA368-C is a three phase four wire 100 Amp per phase prepayment electricity meter operating with 3DES encrypted CPU card. It is used for large residential and light commercial or industrial environments. It is a high profile integration of precision metrology and security technologies.
The meter is equiped with a modular commnication unit available with PLC (power line carrier), RF (radio frequency), MODBUS, and GSM networks. LoRa is a type of low power consumptionl. This wireless design adds wings to the metering features and allows the meter to connect with a head-end server for high end AMR AMI functionalities. It supports both real-time data transmission, load profiling record, and classic metering at the same time.
The build-in latch relay serves as a load control device and disconnects on no credit and tamper, and other load shedding command from the back-end servers. Thanks to its compliance with DLMS / COSEM standard, it is interperoable with devices running on the same protocol. The meter is produced in accordance with ISO9001 standards and IP54 rated protective class, in a wide voltage range ( Un -40% +20%) and RF immunity of 30V/m, enabling it to be deployed in very harsh environments. The CA368-C series is also designed to measure both active and reactive energy, and transfer data parameters via a 2400 bps baud rate optical port..
