Description

WITT TVM 4 is used for DC traction power supply to determine the contact line voltage

This is necessary, for example, when individual sections of the DC rail system have to be interconnected, as an electrical connection between the sections may only be made when all voltage values are within a certain threshold value. Potential-free relay contacts indicate whether the driving voltage of the route section is within the permissible threshold value.
The device does not require any auxiliary voltage and is intended for top-hat rail mounting.

Switching thresholds are stored on delivery, the following areas are possible:

U suit 200 V- 700 V VDC +/- 10%
U-waste 150 V- 600 V + -10%
