High Voltage Distribution Module

The Vanner High Voltage Distribution Module (HVDM), is ideal for heavy duty lorry and bus applications using hybrid or pure electric technology. It permits the control, monitoring and distribution of the drive train battery power to auxiliary power take-offs. As with all Vanner equipment, units are rigorously tested to their 'endurance qualification' standards ensuring rugged, reliable and safe operation.

The HVDM incorporates a 2 channel high voltage power take-off featuring;

  • Special multi-stud bus bar for differing power connections and loads
  • Customisable fuse configuration to optimise load protection
  • Temperature monitoring of power connection ensuring maximum power transfer and cable security
  • Voltage verification feedback for 100% connection and load power integrity
  • Short and open circuit diagnostics for rapid auxiliary circuit fault finding
  • Individual input power walk-in pre-charge circuits, ensuring loads are protected from instant-on transients
  • Passive discharge for switched transient suppression
  • High voltage EMI containment
  • Internal diagnostics
  • High voltage safety interlock for maintainer safety
  • SAE J1939 CANBUS monitoring and control data link. Providing vital monitoring and control information to and from vehicle multiplex systems
