Denki Keiki Co., Ltd. NRT Series Transformers for Preventing Interference Waves

Manufacturer: Denki Keiki Co., Ltd.
Model: NRT Series

Features

  • The most suitable coil winding structure for the transformer’s performance and economic design is adopted by the NRT series, resulting in large-capacity, low-cost, high-quality electric transformers.
  • Noise suppression in common modes is enhanced by the incorporation of normal-mode and differential-mode noise removal functions.
  • Electromagnetic interference is effectively suppressed, even in cases where noise propagation through general circuits or connection points is uneven.
  • Complete protection against input and output disturbances or misapplications is provided by the product.
  • Highly advanced technologies for electric insulation, electromagnetic noise reduction, and special manufacturing processes are utilized to ensure the highest performance and reliability.
  • With the rapid progress in miniaturization and high efficiency of electronic devices, low-voltage power supplies and high-frequency technology are effectively utilized.
  • The difficulties in noise countermeasures are reduced, and the technology that maintains noise isolation is improved.
  • The NRT series plays a major role in EMI/EMC countermeasures, with filters and shield technologies focused on enhancing electromagnetic interference suppression for high-efficiency performance.
