External DC Power Supply


  • External power supplies allow you to provide a wide range of input voltages to power your stand-alone converters and chassis. Input voltages of 24 – 60 VDC and 24 – 42 VRMS allow for installation of any standalone media converters in most industrial, telecom and commercial applications, as well as HVAC and building controlled environments.
  • Multiple form factors allow flexibility to meet your application.
  • The stand-alone form factor can be used with all stand-alone media converters.
  • The piggy back form factor allows the power supply to attach directly to the converter and eliminate the power cable commonly found between the power supply and the converter.
  • Once the piggy back supply is attached to the converter, the combined assembly is much easier to wall mount or attach to DIN Rail environments than using a separate supply.
