ebm-papst Fan Speed Controller, 230 V, 2.5A Max, Variable

Variable speed controllers

Variable speed controllers are equipped with an electronic device designed for centrifugal and helical fans.
These continuously control variable speed of rotation of the fans. These fans are driven by induction motors whose speed is adjusted by reducing the supply voltage.
They are anti-interference and single-phase.
They can control one or more fans depending on the maximum permissible current.
They are housed inside a sealed enclosure.
