AD-LU 70 FE

Description

The digital power converter AD-LU 70 FE 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 AD-LU 70 FE is powered by its measuring voltage L1. The current measurement takes place via the current transformer with passing-through hole attached to the back side. For the measurement of higher voltages or currents, external transformer must be used.

AD-LU 70 FE

Application

Measurement and monitoring of all electrical characteristics in electrical systems. Detection of load profiles for energy management systems, e.g. ISO 50001. Recording the energy consumption of individual consumers.
Attention: This is a Class A product according to EN 55011. Additional EMC actions may be necessary when used in small businesses or in residential areas.
