Solid State Power Controllers

Design Criteria, Inc. has developed solid state power controllers (SSPC) and current limiting power controllers (CLPC) to protect and control many types of high power loads.



  • Switching in less than 5 µsec.
  • Magnetically isolated.
  • Digital interface.
  • Current monitor
  • Voltages to 1200 V.
  • Current to 60A.
  • Current limiting capabilities.
  • Scaleable (both voltage and current).
  • Modules can be paralleled for higher currents.
  • Power Distribution Units (PDU)
  • Aircraft
  • Ships
  • Electric vehicles
