The power meter is a compact instrument for measuring and displaying various network parameters in three-phase systems. This power meter can capture energy values from individual consumers or electrical branches. In addition to voltages and currents, it measures apparent, reactive, and active power, as well as active and reactive energy, displaying these on a 68 x 55 mm screen. Furthermore, this power meter features an integrated RS485 interface, allowing for integration into existing systems. Communication via the RS485 interface is conducted using the Modbus RTU protocol, enabling the reading and modification of measurement values and device settings. The power meter is suitable for panel mounting with a cutout of 96 x 96 mm. The delivery includes a transparent door that can be attached to the front, protecting the device from dust and moisture. In addition to its many measurement functions, the power meter offers alarm functions. A stable power supply is of utmost priority for every network operator. To avoid fluctuations in power quality and disturbances, network monitoring, control, and automation must be adjusted and optimized.
