Technical features and valuable quality of the SCR / thyristor trigger firing unit


Reduced Costs

  • Requires no gate drive power
  • Simplifies logistics as it triggers any thyristor up to 690Vrms

Compact design

  • Reduces the PCB size because of its small footprint
  • Absence of a gate drive power supply

 High Reliability

  • Fully tested product
  • Superior electrical isolation
  • All modules have optically-isolated inputs                 (5KV, VDE0884)
  • Performs well in very harsh industrial environments
  • Handles any inductive or high di/dt load due to powerful gate pulse
