Regulated High voltage power supplies

 

 

Constant short circuit shutdown

Overcurrent shutdowns may occur by strongly filter pollution. In this case high voltage turns off and starts up multiple. This may cause an abatement of filter pollution. Exists the problem, which causes overcurrent shutdown, after several start-ups, the device supposes a constant short circuit and turns off high voltage finally.
To detect a constant short circuit, the device counts the number of start-ups. Is this number greater than 80, the device supposes constant short circuit.
Occurs during a time span tRESET_Fehlerzähler of 5s no overcurrent shutdown, the error counter will be reset to 0.



Options to adapt the device to customer specifications:

  • The number of start-ups, which cause device turn-off may be adjusted up to 255.
  • Time span tRESET_Fehlerzähler may be adjusted.
