The CA168-F01 is a multi-function single-phase smart meter with embedded communication. The meter isused to measure electrical energy accurately for commercial and residential customers. The CA168-F01 can be applied to payment (STS compliant). The communication with an optional external keypad(customer interface unit ClU) can be done via power-line communication(PLC), radio frequency(RF) or byc able connection.
Main Features
SRE detection
20 digit STS encryption
Tamper detection and record
IEC62056-21 compliant optical port
Double CT for Phase and Neutral line
Disconnects on overload and no credit
Support prepayment, credit mode and hot swap
Programmable load limit and low credit warning
Split Configuration for Increased Revenue Protection
The CIU (Customer Interface Unit) is optional. The MCU (Metering & Control Unit) and CIU is linked via Mbus 2 wires communication, galvanically-isolated PLC or RF wireless communication, the communication method is on request.
The CIU is installed within consumer’s home, while MCU is installed in a meter cabinet away from consumers.
