Speed controller (maximum/minimum) with housing for infinitely variable fan speed control in the defined range

The speed controller can be operated with all ebm-papst EC fans.
It is supplied with power via the DC output of the fan and provides a 0-10 V signal,
which enables infinitely variable speed control.
A single speed controller can be used to control a number of fans with the same speed specification
.
The maximum and minimum speeds can be changed before commissioning,
to limit the maximum/minimum speed.
