Anti - Tamper Commercial Electric Meter , Optical Port Wireless Power Meter
The CA368-M is a tamper-proof reinforced multi-function three phase four wire electric meter for commercial and inustrial metering environments. It supports unidirectional measurement of active and reactive energy and provides up to four tariffs. The meter operates in four-wire pattern in one, two or three phase configurations as well as three-wire partterns. The meter is compliant with IEC 62053, EN 50670 (MID) in its mechanical spec and is intended to be installed in any situation that also meets these standards.
The meter is designed to detect various tamper including reverse connection, cover opening, magnetic jamming, abnormal blackout, earth missing, current or voltage unbalance. It is intended for revenue protection against tamper and fraud and serves as secured and reliable as well credit dispenser and metrological instruments.
The CA368-M operates with modularized communication unit and offers free selection of communication networks such as PLC, RF, M-bus, GPRS/ GSM, 4G Lte according to local infrastructure conditions. This feature provides utility and service provider maximum flexibility to choose the most suitable communication for meter's connection with AMR / AMI servers.
