MCM263T Multi-channel energy meter provides a compact and robust metering solution; it can enable reliable monitoring of commercial building electrical or industry loads with a low installation cost-per-point by combining sub-metering.
The branch circuit power meter performs real-time metering, measures energy consumption and generation, multi-tariff time-of-use (TOU), and monitors power quality for advanced communications options, including Modbus via RS485 and Ethernet interface. Various combination options of I/O communications provide for extensive reliable data exchange.
Max 18-channel circuits for single-phase circuits(MCM261T) or 6 channels for three-phase circuits (MCM263T). Multiple units can be connected to meter unlimited number of circuits.
The versatility of MCM263T multi-channel power meters is ideal for multi-tenant or departmental metering applications within office towers, condominiums, apartment buildings, shopping centers, and other multi-user environments
