Pulse transformers for THT mounting

Free Sample Request

13 Variants


Description

  • High insulation rating (>3.2 kVAC) between the primary and the secondary windings
  • High insulation rating up to 500V between the secondary windings
  • Small coupling capacitances between primary and secondary windings limit transient feedback from the power supply side to the control electronics
  • The defined partial discharge voltage guarantees an effecively unlimited serviceable live

Applications

  • Galvanic separation of drive- and power-circuit
  • Mainly used in ignition circuits with Thyristors, Triacs, power transistors and IGBT's
