0647

• the unit controls the motor speed in dependence of a potentiometer value or a atteched control voltage.
• output current 15A, short cut protected.
• 1 potentiometer can drive 10 units.

The blower controller  DRM 647 is used for controlling the rotation speed of dc motors in dependence of a atteched
control voltage. The modul is short cut protected.
It is possible to connect 10 muduls to 1 potentiometer.

0631

• the unit controls the motor speed in dependence of a potentiometer value or a atteched control voltage.
• output current 15A, short cut protected.
• 1 potentiometer can drive 5 units.

The blower controller  EGS 0632 is used for controlling the rotation speed of dc motors in dependence of a atteched
control voltage. The modul is short cut protected.
It is possible to connect 5 moduls to 1 potentiometer.

The input voltage can be a dc control voltage or a  pulse-width modulated voltage.

0632

• The modul controls dc motors of valves or flaps.  selfcalibrating
• output 150mA, short cut protected

With an external potentiometer or voltage a angle is selected.
The motor with position feedback is driven until the feedback
voltage is in accordance with the set point voltage.
