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 for max 18 channels 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 1.0
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.
I/O Option
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;
