Voltage Supervision

Overvoltages or undervoltages in systems often have negative effects on the connected equipment and can bring the whole or parts of the system to a standstill. The EES supervision relays are compactly designed and are suitable for mounting in the distribution cabinet. The voltage supervision is carried out separately for every phase, so not only the mean average value of the voltages, but the actual asymmetry and the individual phase failure is being recognized. In addition the neutral conductor is also monitored on break. Limiting values can be adjusted through potentiometers.

Compact voltage monitoring

EUW-Series

The corresponding types are shown in the datasheet of the EUW-Series.

Under and over voltage supervision with EUW3

  • Voltage supervision per individual phase
  • Switching threshold adjustably
  • Supervision on asymmetry, phase failure and sequence

Sub-voltage supervision with EUW4

  • Voltage supervision per individual phase
  • Switching threshold adjustably or optionally fixed
  • Supervision on asymmetry, phase failure or neutral wire brake
