This potentiometer is developed to control fans equipped with an EC-motor. It is mounted
in a splash water proof housing and can be used for inset as well as for surface mounting.
The potentiometer needs a supply of 230 Vac, and gives a stepless output signal of 0-10 Vdc
or 0-20 mA and PWM between voltage V1 and voltage V2. Position 0 is the off-position. The
load cannot be lower than 2 kΩ (RL≥2 kΩ) in 0-10 V output mode or higher than 500 Ω if
0-20 mA output is selected.
Thanks to their splashproof casing (IP44/54) (for surface-mounting as well as for flushmounting)
they can be used in most demanding (like humid) circumstances (e.g. for kitchens
or bathrooms).
