Electronic motor driven actuators for three-position and modulating control, nominal torque 25 Nm (GBB) or 35 Nm (GIB), 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 power pack).
• 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.
