Product details

The Shelly DC 12V/1A power supply with a 20 m extension cable is an essential addition for the Ecowitt WS90 and Shelly WS90 weather stations. This accessory ensures a reliable power supply necessary for operating the integrated heating of the ultrasonic anemometer. Especially during cold winter months, the heating helps to melt snow and ice, which increases the accuracy of wind measurements even in frosty conditions. The extension cable allows for flexible installation of the weather station in hard-to-reach locations such as roofs or poles, while keeping the power source safely indoors. With this practical accessory, users can optimize the performance of their weather station and capture precise weather data even under extreme conditions.

  • Reliable power supply for weather stations
  • Activates heating for accurate wind measurements
  • Flexible use for outdoor installations
  • Protection of the power source indoors.
