Smart Power Management

DDC Solid State Power Controllers

DDC is the world leader in the design and manufacture of programmable solid state power controllers (SSPC) for military vehicles, with more than 500,000 nodes installed since 1988. In addition to distributing and controlling power with reduced SWaP, protecting loads and wire harnesses with higher reliability and longer life, DDC SSPC’s also enable smart power management that simplifies vehicle power control and provides health and diagnostics that allow the operator to focus their time on other mission critical activities.

DDC Solid-State Power Controllers Enable...

Smart Power Management

  • Intelligent Overcurrent Protection - I2t and Instant Trip Protection, plus Controlled Rise/Fall Time
  • Programmability and Flexibility - Reconfigure, Trip Levels, Channel Paralleling, Power-up Defaults
  • Network Control - Load Channel Control and Status, Load Current and Voltage, Channel Reconfiguration, BIT
  • Vehicle Health and Diagnostics - Autonomous Operation, Load Protection and Monitoring, Alarms (Current, Voltage, Temperature), Power-up Sequencing
