ZH1114 Series

Voltage selector for multi-system railway vehicles

Sensors and high-voltage controlgear

With its voltage and frequency analyzer ZH1114 Schaltbau meets the requirements of modern cross-border traffic.

The ZH1114 identifies the voltage ranges according to UIC 550 and operates as electronic control device for the Schaltbau change-over unit, which adapts the individual loads of the railway vehicle to the different detected supply voltages. Additionally, the correct electrical configuration is being tested by the device.


  • Identification of UIC 550 compliant voltages (1 kV 16 ⅔ Hz / 1.5 kV 50 Hz / 1.5 kV DC / 3 kV DC) and 3 kV 50 Hz
  • Meets insulation requirements for 3 kV DC (UIC 550) acc. to EN 50124-1:2001+A1
  • Customised setting of the device via PC – same hardware for different configurations
  • Application: Adapting the electrical configuration of RIC passenger
    coaches to the detected supply voltage
