POWER DISTRIBUTION UNIT (PDU)

  • Current, voltage and power monitoring 
  • Prepared for functional safety “switch-off”
  • Integrated potential equalization and EMC concept
  • Interlock

Distribution unit
The power distribution unit “PDU” is an intelligent high-voltage distribution unit, which connects power generators and consumers via high-voltage connectors. The PDU can be used with both diesel-electric and battery-electric applications.

Complete solution 
With the PDU, we are offering a complete solution adapted to customer requirements; this includes the number of high-voltage components connected, the installation space in the vehicle and the transferable power as well as the intermediate circuit voltage. Fuses, switches, insulation monitors and power measurement units are installed into the standard series PDU to guarantee the required safety standards. 
Optionally, a pre-charging unit to control the connection currents can be integrated. 

Advantages

  • The PDU housing is compact and provides an optimized solution for the existing installation space 
  • The integrated safety electronics and the safety switch-off function guarantee safe energy distribution
  • Individual switch-off possible via contactors 
  • Like all STW powerMELA products, the PDU is characterized by its field-tested robustness.

Application
The PDU was used successfully in the funding project “ELIAS”, the development of a battery-electric truck.
