Air damper actuators
GEB...1
Rotary version, AC 24 V / AC 230 V
Electronic motor driven actuators for three-position and modulating control,
nominal torque 15 Nm, self-centering shaft adapter, mechanically adjustable
span between 0...90°, prewired with 0.9 m long connection cables.
Type-specific variations with adjustable offset and span for the positioning
signal, position indicator, feedback potentiometer, self-adaptation of the rotary
angle range, and adjustable auxiliary switches for supplementary functions.
This data sheet provides a brief overview of these actuators. Please refer to the
technical basics in CM2Z4621en for a detailed description as well as information on
safety, engineering notes, mounting and commissioning.
Use
•
For damper areas up to 3 m
2
, 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).
