Description

DAMPER Air damper actuators GMA..1 Rotary version with spring return, AC 24 V / DC 24…48 V / AC 230 V Electronic motor driven actuators for two-position, three-position, and modulating control, nominal torque 7 Nm, with spring return, self-centering shaft adapter, mechanically adjustable span between 0…90°, pre wired with 0.9 m long connection cables. Description: For damper areas up to 1.5 m , friction-dependent. In ventilation sections where the actuator must move to the zero position (emergency position) during power failure. For dampers having two actuators on the same damper shaft (tandem-mounted actuators or Power pack). Type-specific variations with adjustable offset and span for the positioning signal, position indicator, feedback potentio meter and adjustable auxiliary switches for supplementary functions. This data sheet provides a brief overview of these actuators.
