The power meter is a compact instrument for measuring and displaying various network parameters in three-phase networks. This power meter can record the energy values of individual consumers or electrical feeders. In addition to the voltages and currents, the apparent, reactive and active power as well as the active and reactive energy are measured and shown on the 68 x 55 mm display. Furthermore, an RS485 interface is integrated into this power meter, which enables integration into existing systems. The RS485 interface communicates using the Modbus RTU protocol. This makes it possible to read out measured values from the power meter or to read and change device settings.
The power meter is designed for panel mounting with a cut-out of 96x96 mm. The scope of delivery includes a transparent door that can be attached to the front to protect the device against dust and moisture. In addition to the many measuring functions, the power meter offers alarm functions. A stable power supply is a top priority for every network operator. To avoid fluctuations in power quality and faults, grid monitoring, control and automation must be adapted and optimised.
