VLDM: continuous monitoring of SDS and HVL

The VLDM measurement and communication module continuously monitors the operation of your VLD (DIN 50526-02, Class 1 or 2.x, or SDS or HVL). The VLDM detects a ‘breakdown’ or a ‘short circuit’ and can report these events in various ways.

Various power sources are available for the ultra-low-power component (battery, auxiliary power supplies and traction current).
