SIEMENS DAMPER ACTUATOR GMA

SIEMENS DAMPER ACTUATOR GMA

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 datasheet provides a brief overview of these actuators. Please refer to the technical basics in CM2Z4614en for a detailed description as well as information on safety, engineering notes, mounting and commissioning.
