Electronic motor driven actuators for two-position, three-position, and modulating control, nominal torque 18 Nm, with spring return, self-centering
shaft adapter, mechanically adjustable span between 0…90°, pre-wired with 0.9 m long connection cables. Type-specific variations with adjustable offset and span for the positioning signal, position indicator, feedback potentiometer and adjustable auxiliary switches for supplementary functions.

• For damper areas up to 4 m2 (GBB) or 6 m2 (GIB), friction-dependent
• Suitable for modulating controllers (DC 0…10 V) or three-position controllers (e.g. for outside air dampers).
• For dampers having two actuators on the same damper shaft (tandem-mounted actuators or powerpack).
• It is recommended to switch off the power during two-position control when the actuator has reached the open or close position, in order to enhance life span and reduce power consumption.
