Description
The MMW family of multimeters and energy analyzers reads and calculates electrical quantities. The energy analyzer, besides being a multimeter, also monitors, analyzes and controls an electrical system. It is suitable for advanced applications such as energy measurement, recording of electrical parameters, programmable digital inputs and outputs.
It allows viewing and recording current, voltage, power factor, power, demand, energy and harmonics, including the minimum and maximum values of such quantities. For integration and communication with other systems, it has digital inputs and outputs, alarm relays and RS485 isolated serial port with Modbus-RTU protocol.
