Iskraemeco MT880 3-Phase Industrial Energy Meter (High-Precision, CT / Direct Connected)
Description:
The Iskraemeco MT880 is a high-precision, multi-functional 3-phase energy meter designed for demanding industrial and commercial energy metering applications. It provides comprehensive energy measurement, load profiling, advanced tariff management, power quality monitoring, and secure communication interfaces.
The meter supports direct connected, CT-connected, and CT/VT configurations, making it suitable for low-voltage, medium-voltage, and high-voltage metering environments. With bi-directional energy measurement, it is also ideal for renewable energy systems such as solar PV installations where both import and export energy flows must be monitored.
The MT880 integrates seamlessly with SCADA systems, AMR/AMI platforms, and building management systems through multiple communication interfaces including optical port, RS-232, RS-485, Ethernet, and optional modem communication. It supports industry-standard protocols such as DLMS/COSEM and MODBUS for reliable system integration.
Built with advanced anti-tampering protection, event logging, and integrated power quality monitoring, the MT880 provides utilities and energy managers with accurate, secure, and detailed energy data for billing, monitoring, and network analysis.
