AD-LU 40 GT, AD-LU 40S GT

Description

The digital power converter AD-LU 40 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 40 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 40-S GT). The current measurement takes place via the throughput converters attached to the front. For the measurement of higher voltages or currents, 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. Thus, without any great effort, all measured values can be displayed.

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. Monitoring of voltage quality variables, e.g. Harmonics.
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.

Specific characteristics

  • Connection of 4-wire systems of any load
  • Measurement of currents, voltages, power, power factors, frequency, harmonics
  • Low power loss during current measurement thanks to integrated through-current transformers
  • Counters for applied and feedback energies
  • Counters for inductive and capacitive reactive power
