U-Clamp Frame Drop-Through Shroud with Feet

  • Page Updated 31 Jul 2017.
  • Alternative shape for VTF12846.
  • Full data fir VTF13167 range.

  • A range of Laminated Transformers optimised for use in Valve Filament and Heater applications.
  • These transfomers feature high isolation voltage between windings.

  • Low External Magnetic Field for Low Hum Generation.
  • Professional quality materials.
  • Varnish Impregnated for Low Acoustic noise.
  • Compliant with current safety requirements.
  • Fully isolated for operation on DC Rails up to 1000 Volts (or more - see individual notes below).
  • Various Voltage and Current Combinations.
  • Special versions made to order.
  • Several styles available for most designs.
  • Magnetron Filament range with high voltage isolation.
