Three-phase
CA368-CT57
CT-Connected Three-Phase Split-Type Energy Meter
The CA368-CT57 is a current transformer(CT)operated threephase multi-functions with modular design. The meter isideal for large residential homes, small commercial andindustrial applications. The communication module isexchangeable ,support PLC/RF/. The CA368-CT57 complieswith the DLMS communication protocol. The built-in tariffstructures are supporting active,reactive and apparentmeasurement modes.
Introduction
Introduction
Split Configuration for Increased Revenue Protection
The meter consists of two parts, the MCU (Metering & Control Unit) and CIU (Customer Interface Unit). The MCU and CIU is linked via galvanically-isolated 2-wire communication cable or RF communication is also available on request.
The CIU is installed within consumer’s home for prepaid token input and info inquiry, while MCU is installed in a meter cabinet away from consumers.
