Universal Transient Barrier, Dual Pair Single Power


  • Compact design universal transient barrier provides protection of low-voltage circuits and transducers
  • Separate plug and base design allows hot swappable module replacement
  • Multi-stage protection and fine over-voltage protection helps ensure lowest residual surge voltages reach sensitive equipment
  • Common-mode and differential-mode protection protects against both possible surge conditions
  • Designed for compact protection of signal and power supply in one compact housing
