Design and Advantages

  • PoE Transformers has been widely used to deliver power and data over a single cable to devices.
  • PoE Transformers standards are evolving to meet the requirement for higher power, up to 90W PD input power.
  • PoE Transformers standards isolation transformers and common mode chokes for both the transmit and receive sections.
  • The center-tapped 1:1 transformers are used for injecting current, and common mode chokes are used to filter out EMI.
  • Auto Xfmr provides more efficient isolation.
