Split-Type Prepaid Smart Meter
Split-Type Three-Phase Prepaid Smart Meter With Keypad (STS Compliant)
CA168-SF43 is our new generation of Din-rail single-phase electricity meter, with accuracy of Class 1,and its shell is made of polycarbonate flame retardant material.This meter is equipped with a current isolation wire and also supports dual circuit measurement and relays to bring outstanding tamper detection features. The communication with the external keypad(ClU) can be done with either PLC, RF, or by Cable connection. Its installation requirements are also optional.

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.
