LOW NOISE · HIGH EFFICIENCY
05 / Compact
Toroidal Transformer

Low-noise ring-core efficiency.

Ring-wound on a continuous strip core — minimal stray flux, low audible hum, high efficiency. Ideal where space, acoustic noise or EMI matter.

  • Audio, medical & lab equipment friendly
  • Low idle current, low radiated field
  • Vacuum-impregnated insulation
  • M6 centre-bolt mounting kit included
Efficiency> 95 %
