AD-LU 410 GA


Especially in power plant operations but also in many other switchgear areas, active power for the optimization and control of processes must be continuously measured. The power converter AD-LU 410 GA is always adapted to the individual case by means of plant-specific adaptations. The nominal voltage, the power to be measured and the desired output signal are required by the customer. The exact power values are available as standard signal for further processing.

AD-LU 410 GA


Measurement of the active power in switchgear, power plants, voltage distributions and transformation into an analog standard signal.

Specific characteristics

  • Plug and play installation due to customer-specific production
  • Fast response time due to analog multipliers
  • Measurement of active power in 3- and 4-wire grids
  • Measurement of symmetrical or asymmetrical load
  • Measurement of active power fed back into the grid
  • Analog output also bipolar possible
  • Separate auxiliary voltage with wide range power supply
