Technical Highlights

  • Continuous grain-oriented silicon core exhibits zero mechanical hum, <5 mG stray magnetic leakage, and superior line regulation.

Application Scenarios

  • Audiophile DACs, CD player power supplies, reference solid-state preamps, and medical lab instrumentation.

Key Features

  • Export-certified R-core power transformer with dual 110VAC universal primary (series 220V or parallel 110V configuration).
  • Precision quad-rail secondary windings (24V 0.5A + dual 13.5V 0.8A + 6V 1A) engineered for high-end audio DACs and preamplifiers.
  • Built-in Faraday electrostatic copper shield with dedicated yellow/green earth lead eliminates high-frequency mains interference.
