AD-LU 45 GT, AD-LU 45S GT

The digital power converter AD-LU 45 GT measures all values of the three-phase power grid such as current, voltage, energy, active, reactive, apparent power and frequency and makes this data available via a fieldbus. The device is therefore ideally suited for integration into energy management systems. The ProfiNet variant contains a 2-port switch for direct forwarding to the next device. 3- or 4-wire networks can be measured. 4-wire networks may have balanced or unbalanced load. 3-wire networks must have balanced load. The AD-LU 45 GT is powered by its measuring voltage L1. However, a variant with separate supply terminals and wide-range power supply is also available (AD-LU 45-S GT).The current measurement takes place via external split-core current transformers, which can be mounted on the wire to be measured without cutting. For the measurement of higher voltages, external converters can be connected at any time. LEDs on the front panel signal the operating state and the data traffic. The compact design and the high performance combined with low energy consumption allow it to be used in almost any application. In addition, the device has a front-sided RS485 interface to which, for example, the TFT display AD-MM 400 can be connected. Somit können ohne großen Aufwand auch vor alle Messwerte angezeigt werden. Thus, without any great effort, all measured values can be displayed.
