Pulse Transformers and Electromagnetic Equipment
The Schaffner range of pulse transformers from Westek Electronics includes single, and fully potted, multi output winding pulse transformers suitable for applications including:
  • Ignition of Triacs, Thyristors, SCRs and IGBT’s
  • Driving bi polar transistors
  • Line coupling for high speed data transmission
  • DC converters with very high galvanic isolation
Power Capacitors
  • Commutation, surge discharge and smoothing
  • Filtering capacitors
  • Buffer storage capacitors for chopper applications
  • Low inductance AC/DC axial design capacitors
  • PCB mounting capacitors and suitable for commutation, smoothing, surge discharge and DC link energy storage
  • Customised designs including customer specific housings
  • High voltage capacitors
  • Power factor correction capacitors
Variac Variable Transformers
  • Continuously variable Dimmerstat auto transformers and voltage stabilisers for applications from the testing of electrical and electronic equipment to power regulation in industrial processes such as plating rectifiers, cathodic protection rectifiers and battery chargers
  • Manually variable auto transformers
  • Air cooled as well as oil cooled types
  • Motor-driven single and three-phase configurations
  • Variable transformers remotely using 4-20 mA process control loops
The Automatic Electric Dimmerstat current range spans from below one amp to several hundreds of amps in oil cooled constructions and Westek Electronics can provide tailor made assemblies to suit virtually any application.

DC Power Supplies
  • Stacking, modular DC DC and AC DC power supplies that are easily customised
