Pulse transformers for THT mounting
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
Standards
-Galvanic separation of drive- and power-circuit
-Mainly used in ignition circuits with Thyristors, Triacs, power transistors
and IGBT's
-DC/DC converters
-Line coupling transformers in high speed data transmission
