DC temperature control for efficient fan speed control and energy saving

For fans from ebm-papst St. Georgen with 2 or 3 wires.
The fan can be controlled within the temperature range between 0% and 100%
and also issues a fan error*, overtemperature and sensor error message
. If this alarm is issued, this temperature control cannot ensure the maximum
speed.
Significant energy savings are possible with this temperature controller.

48V types on request
*only for 3-core fans

ATTENTION: Due to the large number of motor variants, it is possible that a small number of fans (primarily with high speed)
do not work with this control.
