High-voltage power distribution and protection

FLEX power distribution unit (PDU)

The next generation high-voltage intelligent FLEX power distribution unit (PDU) monitors and manages all power distributed to power electronics and provides central protection for the electrical system for commercial vehicles.

Safe and efficient
Provides central protection for the electrical system and manages power distributed to power electronics
Fully-customizable
Assemble elements for a commercial vehicle's specific requirements
Intelligent software
Programmable control of system components and operational status monitoring, communicating status and diagnostics with the vehicle via CAN

Características principais

  • Consists of a series of power distribution elements (PDEs) configured for the specific needs of the system
  • Delivers a completely customized PDU solution with short lead time
  • Software integration into FLEX PDU for complete programmable control of system components
  • Contactor and fuse operational status monitoring that communicates operational status and diagnostics with the vehicle via Controller Area Network (CAN)
  • Seamless over-current protection between fuse(s) and contactor(s) or Breaktor™
  • Optional isolation detection system
