VD1500, VD3000 railway voltage detectors
For rolling stock and infrastructure

Technical data

Utilisation
Electronic detectors for direct voltages.
This device signals the presence of dangerous voltages via
the independent flashing of two LEDs (Light emitting diodes).
A secondary supply voltage is not necessary.
