ZH1800 Series

Flat battery power supply for rail vehicles

Flat battery power supply

Power is supplied to passenger coaches from the locomotive via the train line. Static onboard inverters transform the high voltage from the train line into the desired load voltages. The control voltage necessary for operating the inverters is provided by a vehicle battery.

In the event of a flat battery, the static inverters and contactors are fed by the flat battery power supply for approximately 3 × 3 minutes directly from the high voltage of the train line.

Features

  • Static inverter with power factor adjustment
  • Providing control voltage for static inverters of power supply equipment directly from the train line
  • Suitable for all train lines carrying voltages to UIC 550 and rail vehicles with high-voltage inverters providing power from the train line
  • Operational reliability:
    • Failure free operation and supply with rolling stock
    • No cancellation of train service because of flat batteries
