WITT TVM 4 – Driving Voltage Monitor

The catenary voltage of DC railways must be measured before individual sections can be connected. An electrical connection of those sections may only take place in case all voltage values are within a certain range.


The device monitors the driving voltage of individual sections and supplies information about the voltage values and show if they are within the allowed range. The device does not need any auxiliary power supply and is intended for top-head rail mounting.


If all catenary voltages of the track sections that are to be interconnected lie within the allowed ranges, the interconnection between the track sections can be enabled.
