4 Channel Commercial Electric Meter , Three Wire / Four Wire 3 Phase Kwh Meter
With reputation of quality and innovation, the CA368-M is built up on the basis of classic CA368 three phase foure wire electric meter with extended functionalities for diversity of metrological element measurement and high-end automated smart metering. It is a tamper-proof reinforced multi-rate mete finished in a British Standard 5685 footprint housing, mainly intended for commercial and inustrial environments. The meter type is exclusively designed to optimize the buisness renvenue collection process and ideal for service providers and utilities to manage their tenants power usage and entire grid health.
The CA368-M supports unidirectional measurement for active and reactive energy and offers up to four tariffs and 108 holiday settings. The meter operates in four-wire pattern in one, two or three phase configurations as well as three-wire partterns. The meter is manfuactured by IEC 62053, EN 50670 (MID) in its mechanical spec , and ISO9001 standards with rugged RF immunity withstand of 30Vm, allowing it to be installed in very harsh environmens.
The CA368-M operates with wireless communication such as PLC, RF, M-bus, GPRS/ GSM, 4G Lte according to local infrastructure, allowing it to be connected with a back-end central server for AMR AMI smart metering applications. This feature offers utility and service provider free choice of communication with AMR / AMI setups.
