Mean Well DIN-Rail DC-DC converter 12V to 48V

Original price was: $99.96.Current price is: $83.30.

Mean Well DIN-Rail DC-DC converter 12V to 48V (adjustable up to 56VDC)

  • This is the best DC-DC converter for use with a Starlink Standard Antenna DC Conversion.
  • Works with the Yaosheng Starlink POE and Cable Adapters to convert your Starlink Standard antenna to 12VDC operation as safely as can be done.
  • Low Noise, Adjustable DC voltage output to compensate for voltage drop over the length of the Starlink antenna cable.

These are the same high quality power supplies used in NarwhalDX Wi-Fi Onboard Systems

  • 12VDC Input (9-14VDC)
  • 48VDC Output (48-56VDC Adjustable)
  • 100 Watt Nominal Rating
