The MCM1000 Series provides a compact and robust metering solution, enable reliable monitoring of building electrical loads with a low installation cost-per-point by combining sub-metering. The unit performs real-time metering, measures energy consumption, multi-tariff time-of-use (TOU) and monitors power quality for max 18 channel circuits for single phase or 6 channel for three phase circuits.
Advanced communications options including Modbus via RS485, I/O communications provide for extensive reliable data exchange. Multiple units can be connected together to meter unlimited number of circuits. The versatility of MCM1000 meters are ideal for multi-tenant or departmental metering applications within office towers, condominiums, apartment buildings, shopping centers and other multi-user environments.

Energy (kWh) measurement meeting international standards, accuracy is Class 0.5. It optional Time of Use feature: 12 Seasons, 4 Tariffs record, max three month data for each channel.
Over/Under Limit Alarming
Users can select parameters and set their set points. An alarm will be triggered when the setpoint is reached. At the same time, sound and light signals could be sent out via relay output. The time and reason of an alarm event will be recorded.
Power Quality Analysis
Optional power quality parameters such as voltage and current THD, Odd harmonic distortion (Total Odd HD), even harmonic distortion (Total Even HD), 2 ~ 31 times the harmonic content, Current K-factor (KF), crest factor (CF), telephone interference factor (THFF), voltage and current unbalance etc.
Standard output ports provide energy (kWh) pulse output and time pulse output; optional 6 channel digital inputs (DI) provide pulse counting from water, electricity and gas meter, and monitor switch status; optional 2 channel relay outputs (DO) react upon alarming conditions.
Communication and Network
Supports RS485 communication open protocol: Modbus RTU;
