The MCM243T Multi-Channel Energy Meter is a high-performance metering solution integrating multi-circuit measurement, energy monitoring, and power quality analysis. A single device supports real-time monitoring of 4 branch circuits, helping reduce installation space and metering cost per point in commercial, industrial, and multi-user power distribution systems.
The MCM243T comes standard with RS485/ Modbus RTU communication, 1 pulse output (PO), and 1 SPDT relay output (DO). It also integrates advanced functions including Time-of-Use (TOU), demand measurement, harmonic analysis up to the 31st order, SOE event recording, RTC, and current/voltage unbalance monitoring, providing comprehensive data for energy management, load analysis, and power quality assessment.
