Product description

 

In order to achieve higher efficiencies and to reduce line losses, inverters with a higher output voltage than the usual 3AC 400 V are often used in large on-site generation systems.
So that the grid and system protection can monitor this high voltage, it must be reduced. This is usually done with voltage converters. With the VG1200 coupling device, an ohmic voltage divider is available that takes on this task. In conjunction with the VG1200 coupling device, the UFR1002IP can measure voltages of up to 1200 V. The display in the UFR1002IP is scalable. This means that the voltages at the input of the VG1200 are displayed and the limits for protection against over- and undervoltage are set accordingly. Both devices together meet the requirements of VDE-AR-N 4110 (feeding into the medium-voltage grid).

  • Measuring of voltage up to 1200 V
  • Measuring tolerance ≤ 1,2% of nominal voltage (of UFR1002IP)
  • No voltage converters required
  • Display of the correct voltage on the UFR1002IP (scalable)
  • No supply voltage required
  • Housing V6, 105 mm wide
