The power meter can determine the most important system parameters of a single-phase network. Based on the current and voltage, the power meter calculates the apparent, active and reactive power, as well as the phase difference angle and the power factor. The power meter can also determine the average power for a 15 minute period and the average voltage for a 10 minute period. By using transducers, the measuring range of the power meter can be extended.
The settings can be adjusted via the buttons on the front site of the power meter. It is also possible to program threshold values, which trigger a signal through the two alarm outputs. In addition, the colour of the display can be changed, depending on the actual measuring value. The power meter is available with different measuring units, outputs and power supplies. You can select the particular parameters further below.
